Overview
HTML5 doctype
We use HTML elements and CSS properties that require the use of the HTML5 doctype.
<!DOCTYPE html>
<html lang="en">
...
</html>
Mobile first
Mobile first styles can be found throughout the entire library instead of in separate files.
To ensure proper rendering and touch zooming, add the viewport meta tag to your <head>.
<meta name="viewport" content="width=device-width, initial-scale=1">
Typography and links
Bootstrap sets basic global display, typography, and link styles. Specifically, we:
- Set
background-color: #fff;on thebody - Use the
@font-family-base,@font-size-base, and@line-height-baseattributes as our typographic base - Set the global link color via
@link-colorand apply link underlines only on:hover
These styles can be found within scaffolding.less.
Normalize.css
For improved cross-browser rendering, we use Normalize.css, a project by Nicolas Gallagher and Jonathan Neal.
Containers
Bootstrap requires a containing element to wrap site contents and house our grid system. You may choose one of two containers to use in your projects. Note that, due to padding and more, neither container is nestable.
Use .container for a responsive fixed width container.
<div class="container">
...
</div>Use .container-fluid for a full width container, spanning the entire width of your viewport.
<div class="container-fluid">
...
</div>Buttons
Button tags
Use the button classes on an <a>, <button>, or <input> element. Be sure to check out the links section for more options!
<a class="btn btn-default" href="#" role="button">Link</a>
<button class="btn btn-default" type="submit">Button</button>
<input class="btn btn-default" type="button" value="Input">
<input class="btn btn-default" type="submit" value="Submit">Context-specific usage
While button classes can be used on <a> and <button> elements, only <button> elements are supported within nav and navbar components.
Links acting as buttons
If the <a> elements are used to act as buttons – triggering in-page functionality, rather than navigating to another document or section within the current page – they should also be given an appropriate role="button".
Cross-browser rendering
As a best practice, we highly recommend using the <button> element whenever possible to ensure matching cross-browser rendering.
Among other things, there's a bug in Firefox <30 that prevents us from setting the line-height of <input>-based buttons, causing them to not exactly match the height of other buttons on Firefox.
Options
Use any of the available button classes to quickly create a styled button.
<!-- Standard button -->
<button type="button" class="btn btn-default">Default</button>
<!-- Provides extra visual weight and identifies the primary action in a set of buttons -->
<button type="button" class="btn btn-primary">Primary</button>
<!-- Provides extreme awareness through the use of MineralBay orange -->
<button type="button" class="btn btn-attention">Attention</button>
<!-- Indicates a successful or positive action -->
<button type="button" class="btn btn-success">Success</button>
<!-- Contextual button for informational alert messages -->
<button type="button" class="btn btn-info">Info</button>
<!-- Indicates caution should be taken with this action -->
<button type="button" class="btn btn-warning">Warning</button>
<!-- Indicates a dangerous or potentially negative action -->
<button type="button" class="btn btn-danger">Danger</button>
<!-- Deemphasize a button by making it look like a link while maintaining button behavior -->
<button type="button" class="btn btn-link">Link</button>
<!-- Deemphasize a button by making it look like a link (with danger color) while maintaining button behavior -->
<button type="button" class="btn btn-link text-danger">Danger</button>
<!-- Deemphasize a button by making it look like a link (with success color) while maintaining button behavior -->
<button type="button" class="btn btn-link text-success">Success</button>
Icon-only buttons
Add .btn-icon for icon-only buttons. The .btn-icon class reduces left and right button padding so that the button shape is square. In the example below, notice that contextual color classes can be added to any icon.
<button type="button" class="btn btn-default btn-lg btn-icon"><span class="glyphicon glyphicon-heart" aria-hidden="true"></span></button>
<button type="button" class="btn btn-default btn-icon"><span class="glyphicon glyphicon-heart" aria-hidden="true"></span></button>
<button type="button" class="btn btn-default btn-sm btn-icon"><span class="glyphicon glyphicon-heart" aria-hidden="true"></span></button>
<button type="button" class="btn btn-default btn-xs btn-icon"><span class="glyphicon glyphicon-heart" aria-hidden="true"></span></button>
<button type="button" class="btn btn-default btn-lg btn-icon"><span class="glyphicon glyphicon-heart text-danger"></span></button>
<button type="button" class="btn btn-default btn-icon"><span class="glyphicon glyphicon-heart text-success"></span></button>
<button type="button" class="btn btn-default btn-sm btn-icon"><span class="glyphicon glyphicon-heart text-attention"></span></button>
<button type="button" class="btn btn-default btn-xs btn-icon"><span class="glyphicon glyphicon-heart text-info"></span></button>
Sizes
Fancy larger or smaller buttons? Add .btn-lg, .btn-sm, or .btn-xs for additional sizes.
<button type="button" class="btn btn-primary btn-lg">Large button</button>
<button type="button" class="btn btn-default btn-lg">Large button</button>
<button type="button" class="btn btn-default btn-lg"><span class="glyphicon glyphicon-heart" aria-hidden="true"></span> Large button</button>
<button type="button" class="btn btn-default btn-lg btn-icon"><span class="glyphicon glyphicon-heart" aria-hidden="true"></span></button>
<button type="button" class="btn btn-primary">Default button</button>
<button type="button" class="btn btn-default">Default button</button>
<button type="button" class="btn btn-default"><span class="glyphicon glyphicon-heart" aria-hidden="true"></span> Default button</button>
<button type="button" class="btn btn-default btn-icon"><span class="glyphicon glyphicon-heart" aria-hidden="true"></span></button>
<button type="button" class="btn btn-primary btn-sm">Small button</button>
<button type="button" class="btn btn-default btn-sm">Small button</button>
<button type="button" class="btn btn-default btn-sm"><span class="glyphicon glyphicon-heart" aria-hidden="true"></span> Small button</button>
<button type="button" class="btn btn-default btn-sm btn-icon"><span class="glyphicon glyphicon-heart" aria-hidden="true"></span></button>
<button type="button" class="btn btn-primary btn-xs">Extra small button</button>
<button type="button" class="btn btn-default btn-xs">Extra small button</button>
<button type="button" class="btn btn-default btn-xs"><span class="glyphicon glyphicon-heart" aria-hidden="true"></span> Extra Small button</button>
<button type="button" class="btn btn-default btn-xs btn-icon"><span class="glyphicon glyphicon-heart" aria-hidden="true"></span></button>
Create block level buttons—those that span the full width of a parent— by adding .btn-block.
<button type="button" class="btn btn-primary btn-lg btn-block">Block level button</button>
<button type="button" class="btn btn-default btn-lg btn-block">Block level button</button>
<button type="button" class="btn btn-default btn-lg btn-block"><span class="glyphicon glyphicon-heart" aria-hidden="true"></span> Block level button</button>
Active state
Buttons will appear pressed (with a darker background, darker border, and inset shadow) when active. For <button> elements, this is done via :active. For <a> elements, it's done with .active. However, you may use .active on <button>s should you need to replicate the active state progammatically.
Button element
No need to add :active as it's a pseudo-class, but if you need to force the same appearance, go ahead and add .active.
<button type="button" class="btn btn-primary btn-lg active">Primary button</button>
<button type="button" class="btn btn-default btn-lg active">Button</button>
Anchor element
Add the .active class to <a> buttons.
<a href="#" class="btn btn-primary btn-lg active" role="button">Primary link</a>
<a href="#" class="btn btn-default btn-lg active" role="button">Link</a>
Disabled state
Make buttons look unclickable by fading them back with opacity.
Button element
Add the disabled attribute to <button> buttons.
<button type="button" class="btn btn-lg btn-primary" disabled="disabled">Primary button</button>
<button type="button" class="btn btn-default btn-lg" disabled="disabled">Button</button>
Cross-browser compatibility
If you add the disabled attribute to a <button>, Internet Explorer 9 and below will render text gray with a nasty text-shadow that we cannot fix.
Anchor element
Add the .disabled class to <a> buttons.
<a href="#" class="btn btn-primary btn-lg disabled" role="button">Primary link</a>
<a href="#" class="btn btn-default btn-lg disabled" role="button">Link</a>
We use .disabled as a utility class here, similar to the common .active class, so no prefix is required.
Link functionality caveat
This class uses pointer-events: none to try to disable the link functionality of <a>s, but that CSS property is not yet standardized and isn't fully supported in Opera 18 and below, or in Internet Explorer 11. In addition, even in browsers that do support pointer-events: none, keyboard navigation remains unaffected, meaning that sighted keyboard users and users of assistive technologies will still be able to activate these links. So to be safe, use custom JavaScript to disable such links.
Forms
Basic example
Individual form controls automatically receive some global styling. All textual <input>, <textarea>, and <select> elements with .form-control are set to width: 100%; by default. Wrap labels and controls in .form-group for optimum spacing.
<form role="form">
<div class="form-group">
<label for="exampleInputEmail1">Email address</label>
<input type="email" class="form-control" id="exampleInputEmail1" placeholder="Enter email">
</div>
<div class="form-group">
<label for="exampleInputPassword1">Password</label>
<input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">
</div>
<div class="form-group">
<label for="exampleInputFile">File input</label>
<input type="file" id="exampleInputFile">
<p class="help-block">Example block-level help text here.</p>
</div>
<div class="checkbox">
<label>
<input type="checkbox"> Check me out
</label>
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
Don't mix form groups with input groups
Do not mix form groups directly with input groups. Instead, nest the input group inside of the form group.
Inline form
Add .form-inline to your <form> for left-aligned and inline-block controls. This only applies to forms within viewports that are at least 768px wide.
May require custom widths
Inputs and selects have width: 100%; applied by default in Bootstrap. Within inline forms, we reset that to width: auto; so multiple controls can reside on the same line. Depending on your layout, additional custom widths may be required.
Always add labels
Screen readers will have trouble with your forms if you don't include a label for every input. For these inline forms, you can hide the labels using the .sr-only class. There are further alternative methods of providing a label for assistive technologies, such as the aria-label, aria-labelledby or title attribute. If none of these is present, screen readers may resort to using the placeholder attribute, if present, but note that use of placeholder as a replacement for other labelling methods is not advised.
<form class="form-inline">
<div class="form-group">
<label for="exampleInputName2">Name</label>
<input type="text" class="form-control" id="exampleInputName2" placeholder="Jane Doe">
</div>
<div class="form-group">
<label for="exampleInputEmail2">Email</label>
<input type="email" class="form-control" id="exampleInputEmail2" placeholder="jane.doe@example.com">
</div>
<button type="submit" class="btn btn-default">Send invitation</button>
</form><form class="form-inline" role="form">
<div class="form-group">
<label class="sr-only" for="exampleInputEmail2">Email address</label>
<input type="email" class="form-control" id="exampleInputEmail2" placeholder="Enter email">
</div>
<div class="form-group">
<label class="sr-only" for="exampleInputPassword2">Password</label>
<input type="password" class="form-control" id="exampleInputPassword2" placeholder="Password">
</div>
<div class="checkbox">
<label>
<input type="checkbox"> Remember me
</label>
</div>
<button type="submit" class="btn btn-default">Sign in</button>
</form>
<form class="form-inline">
<div class="form-group">
<label class="sr-only" for="exampleInputAmount">Amount (in dollars)</label>
<div class="input-group">
<div class="input-group-addon">$</div>
<input type="text" class="form-control" id="exampleInputAmount" placeholder="Amount">
<div class="input-group-addon">.00</div>
</div>
</div>
<button type="submit" class="btn btn-primary">Transfer cash</button>
</form>Horizontal form
Use Bootstrap's predefined grid classes to align labels and groups of form controls in a horizontal layout by adding .form-horizontal to the form. Doing so changes .form-groups to behave as grid rows, so no need for .row.
<form class="form-horizontal" role="form">
<div class="form-group">
<label for="inputEmail3" class="col-sm-2 control-label">Email</label>
<div class="col-sm-10">
<input type="email" class="form-control" id="inputEmail3" placeholder="Email">
</div>
</div>
<div class="form-group">
<label for="inputPassword3" class="col-sm-2 control-label">Password</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="inputPassword3" placeholder="Password">
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<div class="checkbox">
<label>
<input type="checkbox"> Remember me
</label>
</div>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default">Sign in</button>
</div>
</div>
</form>
Supported controls
Examples of standard form controls supported in an example form layout.
Inputs
Most common form control, text-based input fields. Includes support for all HTML5 types: text, password, datetime, datetime-local, date, month, time, week, number, email, url, search, tel, and color.
Type declaration required
Inputs will only be fully styled if their type is properly declared.
<input type="text" class="form-control" placeholder="Text input">
Input groups
To add integrated text or buttons before and/or after any text-based <input>, check out the input group component.
Textarea
Form control which supports multiple lines of text. Change rows attribute as necessary.
<textarea class="form-control" rows="3"></textarea>
Checkboxes and radios
Checkboxes are for selecting one or several options in a list, while radios are for selecting one option from many.
A checkbox or radio with the disabled attribute will be styled appropriately. To have the <label> for the checkbox or radio also display a "not-allowed" cursor when the user hovers over the label, add the .disabled class to your .radio, .radio-inline, .checkbox, .checkbox-inline, or <fieldset>.
Default (stacked)
<div class="checkbox">
<label>
<input type="checkbox" value="">
Option one is this and that—be sure to include why it's great
</label>
</div>
<div class="checkbox disabled">
<label>
<input type="checkbox" value="" disabled>
Option two is disabled
</label>
</div>
<div class="radio">
<label>
<input type="radio" name="optionsRadios" id="optionsRadios1" value="option1" checked>
Option one is this and that—be sure to include why it's great
</label>
</div>
<div class="radio">
<label>
<input type="radio" name="optionsRadios" id="optionsRadios2" value="option2">
Option two can be something else and selecting it will deselect option one
</label>
</div>
<div class="radio disabled">
<label>
<input type="radio" name="optionsRadios" id="optionsRadios3" value="option3" disabled>
Option three is disabled
</label>
</div>Inline checkboxes and radios
Use the .checkbox-inline or .radio-inline classes on a series of checkboxes or radios for controls that appear on the same line.
<label class="checkbox-inline">
<input type="checkbox" id="inlineCheckbox1" value="option1"> 1
</label>
<label class="checkbox-inline">
<input type="checkbox" id="inlineCheckbox2" value="option2"> 2
</label>
<label class="checkbox-inline">
<input type="checkbox" id="inlineCheckbox3" value="option3"> 3
</label>
<label class="radio-inline">
<input type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1"> 1
</label>
<label class="radio-inline">
<input type="radio" name="inlineRadioOptions" id="inlineRadio2" value="option2"> 2
</label>
<label class="radio-inline">
<input type="radio" name="inlineRadioOptions" id="inlineRadio3" value="option3"> 3
</label>Checkboxes and radios without label text
Should you have no text within the <label>, the input is positioned as you'd expect. Currently only works on non-inline checkboxes and radios. Remember to still provide some form of label for assistive technologies (for instance, using aria-label).
<div class="checkbox">
<label>
<input type="checkbox" id="blankCheckbox" value="option1" aria-label="...">
</label>
</div>
<div class="radio">
<label>
<input type="radio" name="blankRadio" id="blankRadio1" value="option1" aria-label="...">
</label>
</div>Selects
Use the default option, or add multiple to show multiple options at once.
<select class="form-control">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
<select multiple class="form-control">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
Static control
When you need to place plain text next to a form label within a horizontal form, use the .form-control-static class on a <p>.
<form class="form-horizontal" role="form">
<div class="form-group">
<label class="col-sm-2 control-label">Email</label>
<div class="col-sm-10">
<p class="form-control-static">email@example.com</p>
</div>
</div>
<div class="form-group">
<label for="inputPassword" class="col-sm-2 control-label">Password</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="inputPassword" placeholder="Password">
</div>
</div>
</form>
<form class="form-inline">
<div class="form-group">
<label class="sr-only">Email</label>
<p class="form-control-static">email@example.com</p>
</div>
<div class="form-group">
<label for="inputPassword2" class="sr-only">Password</label>
<input type="password" class="form-control" id="inputPassword2" placeholder="Password">
</div>
<button type="submit" class="btn btn-default">Confirm identity</button>
</form>Focus state
We remove the default outline styles on some form controls and apply a box-shadow in its place for :focus.
Demo :focus state
The above example input uses custom styles in our documentation to demonstrate the :focus state on a .form-control.
Disabled state
Add the disabled boolean attribute on an input to prevent user input and trigger a slightly different look.
<input class="form-control" id="disabledInput" type="text" placeholder="Disabled input here..." disabled>
Disabled fieldsets
Add the disabled attribute to a <fieldset> to disable all the controls within the <fieldset> at once.
Caveat about link functionality of <a>
By default, browsers will treat all native form controls (<input>, <select> and <button> elements) inside a <fieldset disabled> as disabled, preventing both keyboard and mouse interactions on them. However, if your form also includes <a ... class="btn btn-*"> elements, these will only be given a style of pointer-events: none. As noted in the section about disabled state for buttons (and specifically in the sub-section for anchor elements), this CSS property is not yet standardized and isn't fully supported in Opera 18 and below, or in Internet Explorer 11, and won't prevent keyboard users from being able to focus or activate these links. So to be safe, use custom JavaScript to disable such links.
Cross-browser compatibility
While Bootstrap will apply these styles in all browsers, Internet Explorer 9 and below don't actually support the disabled attribute on a <fieldset>. Use custom JavaScript to disable the fieldset in these browsers.
<form role="form">
<fieldset disabled>
<div class="form-group">
<label for="disabledTextInput">Disabled input</label>
<input type="text" id="disabledTextInput" class="form-control" placeholder="Disabled input">
</div>
<div class="form-group">
<label for="disabledSelect">Disabled select menu</label>
<select id="disabledSelect" class="form-control">
<option>Disabled select</option>
</select>
</div>
<div class="checkbox">
<label>
<input type="checkbox"> Can't check this
</label>
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</fieldset>
</form>
Readonly state
Add the readonly boolean attribute on an input to prevent user input and style the input as disabled.
<input class="form-control" type="text" placeholder="Readonly input here…" readonly>Validation states
Bootstrap includes validation styles for error, warning, and success states on form controls. To use, add .has-warning, .has-error, or .has-success to the parent element. Any .control-label, .form-control, and .help-block within that element will receive the validation styles.
<div class="form-group has-success">
<label class="control-label" for="inputSuccess1">Input with success</label>
<input type="text" class="form-control" id="inputSuccess1">
</div>
<div class="form-group has-warning">
<label class="control-label" for="inputWarning1">Input with warning</label>
<input type="text" class="form-control" id="inputWarning1">
</div>
<div class="form-group has-error">
<label class="control-label" for="inputError1">Input with error</label>
<input type="text" class="form-control" id="inputError1">
</div>
<div class="has-success">
<div class="checkbox">
<label>
<input type="checkbox" id="checkboxSuccess" value="option1">
Checkbox with success
</label>
</div>
</div>
<div class="has-warning">
<div class="checkbox">
<label>
<input type="checkbox" id="checkboxWarning" value="option1">
Checkbox with warning
</label>
</div>
</div>
<div class="has-error">
<div class="checkbox">
<label>
<input type="checkbox" id="checkboxError" value="option1">
Checkbox with error
</label>
</div>
</div>Control sizing
Set heights using classes like .input-lg, and set widths using grid column classes like .col-lg-*.
Height sizing
Create taller or shorter form controls that match button sizes.
<input class="form-control input-lg" type="text" placeholder=".input-lg">
<input class="form-control" type="text" placeholder="Default input">
<input class="form-control input-sm" type="text" placeholder=".input-sm">
<select class="form-control input-lg">...</select>
<select class="form-control">...</select>
<select class="form-control input-sm">...</select>
Horizontal form group sizes
<form class="form-horizontal">
<div class="form-group form-group-lg">
<label class="col-sm-2 control-label" for="formGroupInputLarge">Large label</label>
<div class="col-sm-10">
<input class="form-control" type="text" id="formGroupInputLarge" placeholder="Large input">
</div>
</div>
<div class="form-group form-group-sm">
<label class="col-sm-2 control-label" for="formGroupInputSmall">Small label</label>
<div class="col-sm-10">
<input class="form-control" type="text" id="formGroupInputSmall" placeholder="Small input">
</div>
</div>
</form>Column sizing
Wrap inputs in grid columns, or any custom parent element, to easily enforce desired widths.
<div class="row">
<div class="col-xs-2">
<input type="text" class="form-control" placeholder=".col-xs-2">
</div>
<div class="col-xs-3">
<input type="text" class="form-control" placeholder=".col-xs-3">
</div>
<div class="col-xs-4">
<input type="text" class="form-control" placeholder=".col-xs-4">
</div>
</div>
Help text
Block level help text for form controls.
<span class="help-block">A block of help text that breaks onto a new line and may extend beyond one line.</span>
Grid system
Bootstrap includes a responsive, mobile first fluid grid system that appropriately scales up to 12 columns as the device or viewport size increases. It includes predefined classes for easy layout options, as well as powerful mixins for generating more semantic layouts.
Introduction
Grid systems are used for creating page layouts through a series of rows and columns that house your content. Here's how the Bootstrap grid system works:
- Rows must be placed within a
.container(fixed-width) or.container-fluid(full-width) for proper alignment and padding. - Use rows to create horizontal groups of columns.
- Content should be placed within columns, and only columns may be immediate children of rows.
- Predefined grid classes like
.rowand.col-xs-4are available for quickly making grid layouts. Less mixins can also be used for more semantic layouts. - Columns create gutters (gaps between column content) via
padding. That padding is offset in rows for the first and last column via negative margin on.rows. - The negative margin is why the examples below are outdented. It's so that content within grid columns is lined up with non-grid content.
- Grid columns are created by specifying the number of twelve available columns you wish to span. For example, three equal columns would use three
.col-xs-4. - If more than 12 columns are placed within a single row, each group of extra columns will, as one unit, wrap onto a new line.
- Grid classes apply to devices with screen widths greater than or equal to the breakpoint sizes, and override grid classes targeted at smaller devices. Therefore, e.g. applying any
.col-md-*class to an element will not only affect its styling on medium devices but also on large devices if a.col-lg-*class is not present.
Look to the examples for applying these principles to your code.
Media queries
We use the following media queries in our Less files to create the key breakpoints in our grid system.
/* Extra small devices (phones, less than 768px) */
/* No media query since this is the default in Bootstrap */
/* Small devices (tablets, 768px and up) */
@media (min-width: @screen-sm-min) { ... }
/* Medium devices (desktops, 992px and up) */
@media (min-width: @screen-md-min) { ... }
/* Large devices (large desktops, 1200px and up) */
@media (min-width: @screen-lg-min) { ... }We occasionally expand on these media queries to include a max-width to limit CSS to a narrower set of devices.
@media (max-width: @screen-xs-max) { ... }
@media (min-width: @screen-sm-min) and (max-width: @screen-sm-max) { ... }
@media (min-width: @screen-md-min) and (max-width: @screen-md-max) { ... }
@media (min-width: @screen-lg-min) { ... }Grid options
See how aspects of the Bootstrap grid system work across multiple devices with a handy table.
| Extra small devices Phones (<768px) | Small devices Tablets (≥768px) | Medium devices Desktops (≥992px) | Large devices Desktops (≥1200px) | |
|---|---|---|---|---|
| Grid behavior | Horizontal at all times | Collapsed to start, horizontal above breakpoints | ||
| Container width | None (auto) | 750px | 970px | 1170px |
| Class prefix | .col-xs- |
.col-sm- |
.col-md- |
.col-lg- |
| # of columns | 12 | |||
| Column width | Auto | ~62px | ~81px | ~97px |
| Gutter width | 30px (15px on each side of a column) | |||
| Nestable | Yes | |||
| Offsets | Yes | |||
| Column ordering | Yes | |||
Example: Stacked-to-horizontal
Using a single set of .col-md-* grid classes, you can create a basic grid system that starts out stacked on mobile devices and tablet devices (the extra small to small range) before becoming horizontal on desktop (medium) devices. Place grid columns in any .row.
<div class="row">
<div class="col-md-1">.col-md-1</div>
<div class="col-md-1">.col-md-1</div>

</div>Example: Fluid container
Turn any fixed-width grid layout into a full-width layout by changing your outermost .container to .container-fluid.
<div class="container-fluid">
<div class="row">
...
</div>
</div>Example: Mobile and desktop
Don't want your columns to simply stack in smaller devices? Use the extra small and medium device grid classes by adding .col-xs-* .col-md-* to your columns. See the example below for a better idea of how it all works.
<!-- Stack the columns on mobile by making one full-width and the other half-width -->
<div class="row">
<div class="col-xs-12 col-md-8">.col-xs-12 .col-md-8</div>
<div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
</div>
<!-- Columns start at 50% wide on mobile and bump up to 33.3% wide on desktop -->
<div class="row">
<div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
<div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
<div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
</div>
<!-- Columns are always 50% wide, on mobile and desktop -->
<div class="row">
<div class="col-xs-6">.col-xs-6</div>
<div class="col-xs-6">.col-xs-6</div>
</div>Example: Mobile, tablet, desktops
Build on the previous example by creating even more dynamic and powerful layouts with tablet .col-sm-* classes.
<div class="row">
<div class="col-xs-12 col-sm-6 col-md-8">.col-xs-12 .col-sm-6 .col-md-8</div>
<div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
</div>
<div class="row">
<div class="col-xs-6 col-sm-4">.col-xs-6 .col-sm-4</div>
<div class="col-xs-6 col-sm-4">.col-xs-6 .col-sm-4</div>
<!-- Optional: clear the XS cols if their content doesn't match in height -->
<div class="clearfix visible-xs-block"></div>
<div class="col-xs-6 col-sm-4">.col-xs-6 .col-sm-4</div>
</div>Example: Column wrapping
If more than 12 columns are placed within a single row, each group of extra columns will, as one unit, wrap onto a new line.
Since 9 + 4 = 13 > 12, this 4-column-wide div gets wrapped onto a new line as one contiguous unit.
Subsequent columns continue along the new line.
<div class="row">
<div class="col-xs-9">.col-xs-9</div>
<div class="col-xs-4">.col-xs-4<br>Since 9 + 4 = 13 > 12, this 4-column-wide div gets wrapped onto a new line as one contiguous unit.</div>
<div class="col-xs-6">.col-xs-6<br>Subsequent columns continue along the new line.</div>
</div>Responsive column resets
With the four tiers of grids available you're bound to run into issues where, at certain breakpoints, your columns don't clear quite right as one is taller than the other. To fix that, use a combination of a .clearfix and our responsive utility classes.
Resize your viewport or check it out on your phone for an example.
<div class="row">
<div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
<div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
<!-- Add the extra clearfix for only the required viewport -->
<div class="clearfix visible-xs-block"></div>
<div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
<div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
</div>In addition to column clearing at responsive breakpoints, you may need to reset offsets, pushes, or pulls. See this in action in the grid example.
<div class="row">
<div class="col-sm-5 col-md-6">.col-sm-5 .col-md-6</div>
<div class="col-sm-5 col-sm-offset-2 col-md-6 col-md-offset-0">.col-sm-5 .col-sm-offset-2 .col-md-6 .col-md-offset-0</div>
</div>
<div class="row">
<div class="col-sm-6 col-md-5 col-lg-6">.col-sm-6 .col-md-5 .col-lg-6</div>
<div class="col-sm-6 col-md-5 col-md-offset-2 col-lg-6 col-lg-offset-0">.col-sm-6 .col-md-5 .col-md-offset-2 .col-lg-6 .col-lg-offset-0</div>
</div>Offsetting columns
Move columns to the right using .col-md-offset-* classes. These classes increase the left margin of a column by * columns. For example, .col-md-offset-4 moves .col-md-4 over four columns.
<div class="row">
<div class="col-md-4">.col-md-4</div>
<div class="col-md-4 col-md-offset-4">.col-md-4 .col-md-offset-4</div>
</div>
<div class="row">
<div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div>
<div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div>
</div>
<div class="row">
<div class="col-md-6 col-md-offset-3">.col-md-6 .col-md-offset-3</div>
</div>Nesting columns
To nest your content with the default grid, add a new .row and set of .col-sm-* columns within an existing .col-sm-* column. Nested rows should include a set of columns that add up to 12 or less (it is not required that you use all 12 available columns).
<div class="row">
<div class="col-sm-9">
Level 1: .col-sm-9
<div class="row">
<div class="col-xs-8 col-sm-6">
Level 2: .col-xs-8 .col-sm-6
</div>
<div class="col-xs-4 col-sm-6">
Level 2: .col-xs-4 .col-sm-6
</div>
</div>
</div>
</div>Column ordering
Easily change the order of our built-in grid columns with .col-md-push-* and .col-md-pull-* modifier classes.
<div class="row">
<div class="col-md-9 col-md-push-3">.col-md-9 .col-md-push-3</div>
<div class="col-md-3 col-md-pull-9">.col-md-3 .col-md-pull-9</div>
</div>Less mixins and variables
In addition to prebuilt grid classes for fast layouts, Bootstrap includes Less variables and mixins for quickly generating your own simple, semantic layouts.
Variables
Variables determine the number of columns, the gutter width, and the media query point at which to begin floating columns. We use these to generate the predefined grid classes documented above, as well as for the custom mixins listed below.
@grid-columns: 12;
@grid-gutter-width: 30px;
@grid-float-breakpoint: 768px;Mixins
Mixins are used in conjunction with the grid variables to generate semantic CSS for individual grid columns.
// Creates a wrapper for a series of columns
.make-row(@gutter: @grid-gutter-width) {
// Then clear the floated columns
.clearfix();
@media (min-width: @screen-sm-min) {
margin-left: (@gutter / -2);
margin-right: (@gutter / -2);
}
// Negative margin nested rows out to align the content of columns
.row {
margin-left: (@gutter / -2);
margin-right: (@gutter / -2);
}
}
// Generate the extra small columns
.make-xs-column(@columns; @gutter: @grid-gutter-width) {
position: relative;
// Prevent columns from collapsing when empty
min-height: 1px;
// Inner gutter via padding
padding-left: (@gutter / 2);
padding-right: (@gutter / 2);
// Calculate width based on number of columns available
@media (min-width: @grid-float-breakpoint) {
float: left;
width: percentage((@columns / @grid-columns));
}
}
// Generate the small columns
.make-sm-column(@columns; @gutter: @grid-gutter-width) {
position: relative;
// Prevent columns from collapsing when empty
min-height: 1px;
// Inner gutter via padding
padding-left: (@gutter / 2);
padding-right: (@gutter / 2);
// Calculate width based on number of columns available
@media (min-width: @screen-sm-min) {
float: left;
width: percentage((@columns / @grid-columns));
}
}
// Generate the small column offsets
.make-sm-column-offset(@columns) {
@media (min-width: @screen-sm-min) {
margin-left: percentage((@columns / @grid-columns));
}
}
.make-sm-column-push(@columns) {
@media (min-width: @screen-sm-min) {
left: percentage((@columns / @grid-columns));
}
}
.make-sm-column-pull(@columns) {
@media (min-width: @screen-sm-min) {
right: percentage((@columns / @grid-columns));
}
}
// Generate the medium columns
.make-md-column(@columns; @gutter: @grid-gutter-width) {
position: relative;
// Prevent columns from collapsing when empty
min-height: 1px;
// Inner gutter via padding
padding-left: (@gutter / 2);
padding-right: (@gutter / 2);
// Calculate width based on number of columns available
@media (min-width: @screen-md-min) {
float: left;
width: percentage((@columns / @grid-columns));
}
}
// Generate the medium column offsets
.make-md-column-offset(@columns) {
@media (min-width: @screen-md-min) {
margin-left: percentage((@columns / @grid-columns));
}
}
.make-md-column-push(@columns) {
@media (min-width: @screen-md-min) {
left: percentage((@columns / @grid-columns));
}
}
.make-md-column-pull(@columns) {
@media (min-width: @screen-md-min) {
right: percentage((@columns / @grid-columns));
}
}
// Generate the large columns
.make-lg-column(@columns; @gutter: @grid-gutter-width) {
position: relative;
// Prevent columns from collapsing when empty
min-height: 1px;
// Inner gutter via padding
padding-left: (@gutter / 2);
padding-right: (@gutter / 2);
// Calculate width based on number of columns available
@media (min-width: @screen-lg-min) {
float: left;
width: percentage((@columns / @grid-columns));
}
}
// Generate the large column offsets
.make-lg-column-offset(@columns) {
@media (min-width: @screen-lg-min) {
margin-left: percentage((@columns / @grid-columns));
}
}
.make-lg-column-push(@columns) {
@media (min-width: @screen-lg-min) {
left: percentage((@columns / @grid-columns));
}
}
.make-lg-column-pull(@columns) {
@media (min-width: @screen-lg-min) {
right: percentage((@columns / @grid-columns));
}
}Example usage
You can modify the variables to your own custom values, or just use the mixins with their default values. Here's an example of using the default settings to create a two-column layout with a gap between.
.wrapper {
.make-row();
}
.content-main {
.make-lg-column(8);
}
.content-secondary {
.make-lg-column(3);
.make-lg-column-offset(1);
}<div class="wrapper">
<div class="content-main">...</div>
<div class="content-secondary">...</div>
</div>Condensed Grid
Condense the default grid gutter with .row .row-condensed.
<div class="row row-condensed">
...
</div>
Condense the default grid gutter even further with .row .row-xcondensed.
<div class="row row-xcondensed">
...
</div>
Using Condensed Grid
The condensed grid is a custom extension of Bootstrap's grid system. Condensed grids should only be used in components that require condensed spacing for fine tuning design layout. For example, listings cards are small components that make use of columns. The default column gutter width (30px) is too large for use within the context of a card. Therefore it makes sense to use a condensed grid with a more appropriate gutter width.
Helper classes
Contextual colors
Convey meaning through color with a handful of emphasis utility classes.
These may also be applied to a tags and .clickable links and will darken on hover just like our default link styles. See links for more information.
Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.
Nullam id dolor id nibh ultricies vehicula ut id elit.
Duis mollis, est non commodo luctus, nisi erat porttitor ligula.
Maecenas sed diam eget risus varius blandit sit amet non magna.
Etiam porta sem malesuada magna mollis euismod.
Donec ullamcorper nulla non metus auctor fringilla.
Maecenas sed diam eget risus varius blandit sit amet non magna.
<p class="text-muted">...</p>
<p class="text-primary">...</p>
<p class="text-success">...</p>
<p class="text-info">...</p>
<p class="text-warning">...</p>
<p class="text-danger">...</p>
<p class="text-attention">...</p>
Dealing with specificity
Sometimes emphasis classes cannot be applied due to the specificity of another selector. In most cases, a sufficient workaround is to wrap your text in a <span> with the class.
Contextual backgrounds
Similar to the contextual text color classes, easily set the background of an element to any contextual class. Anchor components will darken on hover, just like the text classes.
.bg-primary
.bg-success
.bg-info
.bg-warning
.bg-danger
.bg-attention
.bg-white
.bg-gray-lightest
.bg-gray-lighter
.bg-gray-light
.bg-gray
.bg-gray-dark
.bg-gray-darker
.bg-cool-dark
.bg-cool
.bg-cool-light
<p class="bg-primary">...</p>
<p class="bg-success">...</p>
<p class="bg-info">...</p>
<p class="bg-warning">...</p>
<p class="bg-danger">...</p>
<p class="bg-attention">...</p>
<p class="bg-gray-lightest">...</p>
<p class="bg-gray-lighter">...</p>
<p class="bg-gray-light">...</p>
<p class="bg-gray">...</p>
<p class="bg-gray-dark">...</p>
<p class="bg-gray-darker">...</p>
<p class="bg-cool-dark">...</p>
<p class="bg-cool">...</p>
<p class="bg-cool-light">...</p>
Close icon
Use the generic close icon for dismissing content like modals and alerts.
<button type="button" class="close" aria-hidden="true">×</button>
Carets
Use carets to indicate dropdown functionality and direction. Note that the default caret will reverse automatically in dropup menus.
<span class="caret"></span>
We added a few more carets. Here are your delicious options. By the way, these work great with the :after pseudo class. See table sorting for an example of .caret-up being used in a pseudo class (descending).
<span class="caret-up"></span>
<span class="caret-right"></span>
<span class="caret-left"></span>
Quick floats
Float an element to the left or right with a class. !important is included to avoid specificity issues. Classes can also be used as mixins.
<div class="pull-left">...</div>
<div class="pull-right">...</div>
// Classes
.pull-left {
float: left !important;
}
.pull-right {
float: right !important;
}
// Usage as mixins
.element {
.pull-left();
}
.another-element {
.pull-right();
}
Quick floats not for use in navbars
To align components in navbars with utility classes, use .navbar-left or .navbar-right instead. See the navbar docs for details.
Center content blocks
Set an element to display: block and center via margin. Available as a mixin and class.
<div class="center-block">...</div>
// Classes
.center-block {
display: block;
margin-left: auto;
margin-right: auto;
}
// Usage as mixins
.element {
.center-block();
}
Clearfix
Easily clear floats by adding .clearfix to the parent element. Utilizes the micro clearfix as popularized by Nicolas Gallagher. Can also be used as a mixin.
<!-- Usage as a class -->
<div class="clearfix">...</div>
// Mixin itself
.clearfix() {
&:before,
&:after {
content: " ";
display: table;
}
&:after {
clear: both;
}
}
// Usage as a Mixin
.element {
.clearfix();
}
Showing and hiding content
Force an element to be shown or hidden (including for screen readers) with the use of .show and .hidden classes. These classes use !important to avoid specificity conflicts, just like the quick floats. They are only available for block level toggling. They can also be used as mixins.
.hide is available, but it does not always affect screen readers and is deprecated as of v3.0.1. Use .hidden or .sr-only instead.
Furthermore, .invisible can be used to toggle only the visibility of an element, meaning its display is not modified and the element can still affect the flow of the document.
<div class="show">...</div>
<div class="hidden">...</div>
// Classes
.show {
display: block !important;
}
.hidden {
display: none !important;
visibility: hidden !important;
}
.invisible {
visibility: hidden;
}
// Usage as mixins
.element {
.show();
}
.another-element {
.hidden();
}
Image replacement
Utilize the .text-hide class or mixin to help replace an element's text content with a background image.
<h1 class="text-hide">Custom heading</h1>
// Usage as a Mixin
.heading {
.text-hide();
}
Images
Responsive images
Images in Bootstrap 3 can be made responsive-friendly via the addition of the .img-responsive class. This applies max-width: 100%; and height: auto; to the image so that it scales nicely to the parent element.
SVG images and IE 8-10
In Internet Explorer 8-10, SVG images with .img-responsive are disproportionately sized. To fix this, add width: 100% \9; where necessary. Bootstrap doesn't apply this automatically as it causes complications to other image formats.
<img src="..." class="img-responsive" alt="Responsive image">
Image shapes
Add classes to an <img> element to easily style images in any project.
<img src="..." alt="..." class="img-rounded">
<img src="..." alt="..." class="img-circle">
<img src="..." alt="..." class="img-thumbnail">
Links
Default links
Default link and links with contextual colors.
<a href="">Default anchor tag</a>
<a href="" class="text-muted">Anchor tag text muted</a>
<a href="" class="text-primary">Anchor tag text primary</a>
<a href="" class="text-success">Anchor tag text success</a>
<a href="" class="text-info">Anchor tag text info</a>
<a href="" class="text-warning">Anchor tag text warning</a>
<a href="" class="text-danger">Anchor tag text danger</a>
<a href="" class="text-attention">Anchor tag text attention</a>Clickable links
Sometimes we want anchor tag styles without the anchor tag markup. Use .clickable instead.

For faster mobile-friendly development, use these utility classes for showing and hiding content by device via media query. Also included are utility classes for toggling content when printed.
Try to use these on a limited basis and avoid creating entirely different versions of the same site. Instead, use them to complement each device's presentation.
Available classes
Use a single or combination of the available classes for toggling content across viewport breakpoints.
| Extra small devices Phones (<768px) | Small devices Tablets (≥768px) | Medium devices Desktops (≥992px) | Large devices Desktops (≥1200px) | |
|---|---|---|---|---|
.visible-xs-* |
Visible | Hidden | Hidden | Hidden |
.visible-sm-* |
Hidden | Visible | Hidden | Hidden |
.visible-md-* |
Hidden | Hidden | Visible | Hidden |
.visible-lg-* |
Hidden | Hidden | Hidden | Visible |
.hidden-xs |
Hidden | Visible | Visible | Visible |
.hidden-sm |
Visible | Hidden | Visible | Visible |
.hidden-md |
Visible | Visible | Hidden | Visible |
.hidden-lg |
Visible | Visible | Visible | Hidden |
As of v3.2.0, the .visible-*-* classes for each breakpoint come in three variations, one for each CSS display property value listed below.
| Group of classes | CSS display |
|---|---|
.visible-*-block |
display: block; |
.visible-*-inline |
display: inline; |
.visible-*-inline-block |
display: inline-block; |
So, for extra small (xs) screens for example, the available .visible-*-* classes are: .visible-xs-block, .visible-xs-inline, and .visible-xs-inline-block.
The classes .visible-xs, .visible-sm, .visible-md, and .visible-lg also exist, but are deprecated as of v3.2.0. They are approximately equivalent to .visible-*-block, except with additional special cases for toggling <table>-related elements.
Print classes
Similar to the regular responsive classes, use these for toggling content for print.
| Classes | Browser | |
|---|---|---|
.visible-print-block.visible-print-inline.visible-print-inline-block
|
Hidden | Visible |
.hidden-print |
Visible | Hidden |
The class .visible-print also exists but is deprecated as of v3.2.0. It is approximately equivalent to .visible-print-block, except with additional special cases for <table>-related elements.
Test cases
Resize your browser or load on different devices to test the responsive utility classes.
Visible on...
Green checkmarks indicate the element is visible in your current viewport.
Hidden on...
Here, green checkmarks also indicate the element is hidden in your current viewport.
Tables
Basic example
For basic styling—light padding and only horizontal dividers—add the base class .table to any <table>. It may seem super redundant, but given the widespread use of tables for other plugins like calendars and date pickers, we've opted to isolate our custom table styles.
| # | First Name | Last Name | Username |
|---|---|---|---|
| 1 | Mark | Otto | @mdo |
| 2 | Jacob | Thornton | @fat |
| 3 | Larry | the Bird |
<table class="table">
...
</table>
Striped rows
Use .table-striped to add zebra-striping to any table row within the <tbody>.
Cross-browser compatibility
Striped tables are styled via the :nth-child CSS selector, which is not available in Internet Explorer 8.
| # | First Name | Last Name | Username |
|---|---|---|---|
| 1 | Mark | Otto | @mdo |
| 2 | Jacob | Thornton | @fat |
| 3 | Larry | the Bird |
<table class="table table-striped">
...
</table>
Bordered table
Add .table-bordered for borders on all sides of the table and cells.
| # | First Name | Last Name | Username |
|---|---|---|---|
| 1 | Mark | Otto | @mdo |
| Mark | Otto | @TwBootstrap | |
| 2 | Jacob | Thornton | @fat |
| 3 | Larry the Bird | ||
<table class="table table-bordered">
...
</table>
Hover rows
Add .table-hover to enable a hover state on table rows within a <tbody>.
| # | First Name | Last Name | Username |
|---|---|---|---|
| 1 | Mark | Otto | @mdo |
| 2 | Jacob | Thornton | @fat |
| 3 | Larry the Bird | ||
<table class="table table-hover">
...
</table>
Condensed table
Add .table-condensed to make tables more compact by cutting cell padding in half.
| # | First Name | Last Name | Username |
|---|---|---|---|
| 1 | Mark | Otto | @mdo |
| 2 | Jacob | Thornton | @fat |
| 3 | Larry the Bird | ||
<table class="table table-condensed">
...
</table>
Contextual classes
Use contextual classes to color table rows or individual cells.
| Class | Description |
|---|---|
.active
|
Applies the hover color to a particular row or cell |
.success
|
Indicates a successful or positive action |
.info
|
Indicates a neutral informative change or action |
.warning
|
Indicates a warning that might need attention |
.danger
|
Indicates a dangerous or potentially negative action |
.selected
|
Applies the warning color to a particular row or cell |
| # | Column heading | Column heading | Column heading |
|---|---|---|---|
| 1 | Active | Column content | Column content |
| 2 | Column content | Column content | Column content |
| 3 | Success | Column content | Column content |
| 4 | Column content | Column content | Column content |
| 5 | Info | Column content | Column content |
| 6 | Column content | Column content | Column content |
| 7 | Warning | Column content | Column content |
| 8 | Column content | Column content | Column content |
| 9 | Danger | Column content | Column content |
| 10 | Column content | Column content | Column content |
| 11 | Selected | Column content | Column content |
<!-- On rows -->
<tr class="active">...</tr>
<tr class="success">...</tr>
<tr class="info">...</tr>
<tr class="warning">...</tr>
<tr class="danger">...</tr>
<tr class="selected">...</tr>
<!-- On cells (`td` or `th`) -->
<tr>
<td class="active">...</td>
<td class="success">...</td>
<td class="info">...</td>
<td class="warning">...</td>
<td class="danger">...</td>
<td class="selected">...</td>
</tr>
Responsive tables
Create responsive tables by wrapping any .table in .table-responsive to make them scroll horizontally on small devices (under 768px). When viewing on anything larger than 768px wide, you will not see any difference in these tables.
Vertical clipping/truncation
Responsive tables make use of overflow-y: hidden, which clips off any content that goes beyond the bottom or top edges of the table. In particular, this can clip off dropdown menus and other third-party widgets.
Firefox and fieldsets
Firefox has some awkward fieldset styling involving width that interferes with the responsive table. This cannot be overriden without a Firefox-specific hack that we don't provide in Bootstrap:
@-moz-document url-prefix() {
fieldset { display: table-cell; }
}For more information, read this Stack Overflow answer.

Bootstrap's global default font-size is 14px, with a line-height of 1.428. This is applied to the <body> and all paragraphs. In addition, <p> (paragraphs) receive a bottom margin of half their computed line-height (10px by default).
Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Nullam id dolor id nibh ultricies vehicula.
Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec ullamcorper nulla non metus auctor fringilla. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit. Donec ullamcorper nulla non metus auctor fringilla.
Maecenas sed diam eget risus varius blandit sit amet non magna. Donec id elit non mi porta gravida at eget metus. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit.
<p>...</p>Lead body copy
Make a paragraph stand out by adding .lead.
Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor. Duis mollis, est non commodo luctus.
<p class="lead">...</p>Built with Less
The typographic scale is based on two Less variables in variables.less: @font-size-base and @line-height-base. The first is the base font-size used throughout and the second is the base line-height. We use those variables and some simple math to create the margins, paddings, and line-heights of all our type and more. Customize them and Bootstrap adapts.
Inline text elements
Marked text
For pl-codeing a run of text due to its relevance in another context, use the <mark> tag.
You can use the mark tag to pl-code text.
You can use the mark tag to <mark>highlight</mark> text.Deleted text
For indicating blocks of text that have been deleted use the <del> tag.
This line of text is meant to be treated as deleted text.
<del>This line of text is meant to be treated as deleted text.</del>Strikethrough text
For indicating blocks of text that are no longer relevant use the <s> tag.
This line of text is meant to be treated as no longer accurate.
<s>This line of text is meant to be treated as no longer accurate.</s>Inserted text
For indicating additions to the document use the <ins> tag.
This line of text is meant to be treated as an addition to the document.
<ins>This line of text is meant to be treated as an addition to the document.</ins>Underlined text
To underline text use the <u> tag.
This line of text will render as underlined
<u>This line of text will render as underlined</u>Make use of HTML's default emphasis tags with lightweight styles.
Small text
For de-emphasizing inline or blocks of text, use the <small> tag to set text at 85% the size of the parent. Heading elements receive their own font-size for nested <small> elements.
You may alternatively use an inline element with .small in place of any <small>.
This line of text is meant to be treated as fine print.
