Bootstrap HTML

Example

Toggleable, contextual menu for displaying lists of links. Made interactive with the dropdown JavaScript plugin.

<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu">
  <li><a tabindex="-1" href="#">Action</a></li>
  <li><a tabindex="-1" href="#">Another action</a></li>
  <li><a tabindex="-1" href="#">Something else here</a></li>
  <li class="divider"></li>
  <li><a tabindex="-1" href="#">Separated link</a></li>
</ul>

Markup

Looking at just the dropdown menu, here's the required HTML. You need to wrap the dropdown's trigger and the dropdown menu within .dropdown, or another element that declares position: relative;. Then just create the menu.

<div class="dropdown">
  <!-- Link or button to toggle dropdown -->
  <ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
    <li><a tabindex="-1" href="#">Action</a></li>
    <li><a tabindex="-1" href="#">Another action</a></li>
    <li><a tabindex="-1" href="#">Something else here</a></li>
    <li class="divider"></li>
    <li><a tabindex="-1" href="#">Separated link</a></li>
  </ul>
</div>

Options

Align menus to the right and add include additional levels of dropdowns.

Aligning the menus

Add .pull-right to a .dropdown-menu to right align the dropdown menu.

<ul class="dropdown-menu pull-right" role="menu" aria-labelledby="dLabel">
  ...
</ul>

Disabled menu options

Add .disabled to a <li> in the dropdown to disable the link.

<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu">
  <li><a tabindex="-1" href="#">Regular link</a></li>
  <li class="disabled"><a tabindex="-1" href="#">Disabled link</a></li>
  <li><a tabindex="-1" href="#">Another link</a></li>
</ul>

Examples

Two basic options, along with two more specific variations.

Single button group

Wrap a series of buttons with .btn in .btn-group.

<div class="btn-group">
  <button class="btn">Left</button>
  <button class="btn">Middle</button>
  <button class="btn">Right</button>
</div>

Multiple button groups

Combine sets of <div class="btn-group"> into a <div class="btn-toolbar"> for more complex components.

<div class="btn-toolbar">
  <div class="btn-group">
    ...
  </div>
</div>

Vertical button groups

Make a set of buttons appear vertically stacked rather than horizontally.

<div class="btn-group btn-group-vertical">
  ...
</div>

Checkbox and radio flavors

Button groups can also function as radios, where only one button may be active, or checkboxes, where any number of buttons may be active. View the JavaScript docs for that.

Dropdowns in button groups

Heads up! Buttons with dropdowns must be individually wrapped in their own .btn-group within a .btn-toolbar for proper rendering.

Overview and examples

Use any button to trigger a dropdown menu by placing it within a .btn-group and providing the proper menu markup.

<div class="btn-group">
  <a class="btn dropdown-toggle" data-toggle="dropdown" href="#">
    Action
    <span class="caret"></span>
  </a>
  <ul class="dropdown-menu">
    <!-- dropdown menu links -->
  </ul>
</div>

Works with all button sizes

Button dropdowns work at any size: .btn-large, .btn-small, or .btn-mini.

Requires JavaScript

Button dropdowns require the Bootstrap dropdown plugin to function.

In some cases—like mobile—dropdown menus will extend outside the viewport. You need to resolve the alignment manually or with custom JavaScript.

Split button dropdowns

Building on the button group styles and markup, we can easily create a split button. Split buttons feature a standard action on the left and a dropdown toggle on the right with contextual links.

<div class="btn-group">
  <button class="btn">Action</button>
  <button class="btn dropdown-toggle" data-toggle="dropdown">
    <span class="caret"></span>
  </button>
  <ul class="dropdown-menu">
    <!-- dropdown menu links -->
  </ul>
</div>

Sizes

Utilize the extra button classes .btn-mini, .btn-small, or .btn-large for sizing.

<div class="btn-group">
  <button class="btn btn-mini">Action</button>
  <button class="btn btn-mini dropdown-toggle" data-toggle="dropdown">
    <span class="caret"></span>
  </button>
  <ul class="dropdown-menu">
    <!-- dropdown menu links -->
  </ul>
</div>

Dropup menus

Dropdown menus can also be toggled from the bottom up by adding a single class to the immediate parent of .dropdown-menu. It will flip the direction of the .caret and reposition the menu itself to move from the bottom up instead of top down.

<div class="btn-group dropup">
  <button class="btn">Dropup</button>
  <button class="btn dropdown-toggle" data-toggle="dropdown">
    <span class="caret"></span>
  </button>
  <ul class="dropdown-menu">
    <!-- dropdown menu links -->
  </ul>
</div>

Lightweight defaults Same markup, different classes

All nav components here—tabs, pills, and lists—share the same base markup and styles through the .nav class.

Basic tabs

Take a regular <ul> of links and add .nav-tabs:

<ul class="nav nav-tabs">
  <li class="active">
    <a href="#">Home</a>
  </li>
  <li><a href="#">...</a></li>
  <li><a href="#">...</a></li>
</ul>

Basic pills

Take that same HTML, but use .nav-pills instead:

<ul class="nav nav-pills">
  <li class="active">
    <a href="#">Home</a>
  </li>
  <li><a href="#">...</a></li>
  <li><a href="#">...</a></li>
</ul>

Disabled state

For any nav component (tabs, pills, or list), add .disabled for gray links and no hover effects. Links will remain clickable, however, unless you remove the href attribute. Alternatively, you could implement custom JavaScript to prevent those clicks.

<ul class="nav nav-pills">
  ...
  <li class="disabled"><a href="#">Home</a></li>
  ...
</ul>

Component alignment

To align nav links, use the .pull-left or .pull-right utility classes. Both classes will add a CSS float in the specified direction.

Stackable

As tabs and pills are horizontal by default, just add a second class, .nav-stacked, to make them appear vertically stacked.

Stacked tabs

<ul class="nav nav-tabs nav-stacked">
  ...
</ul>

Stacked pills

<ul class="nav nav-pills nav-stacked">
  ...
</ul>

Dropdowns

Add dropdown menus with a little extra HTML and the dropdowns JavaScript plugin.

Tabs with dropdowns

<ul class="nav nav-tabs">
  <li class="dropdown">
    <a class="dropdown-toggle"
       data-toggle="dropdown"
       href="#">
        Dropdown
        <b class="caret"></b>
      </a>
    <ul class="dropdown-menu">
      <!-- links -->
    </ul>
  </li>
</ul>

Pills with dropdowns

<ul class="nav nav-pills">
  <li class="dropdown">
    <a class="dropdown-toggle"
       data-toggle="dropdown"
       href="#">
        Dropdown
        <b class="caret"></b>
      </a>
    <ul class="dropdown-menu">
      <!-- links -->
    </ul>
  </li>
</ul>

Nav lists

A simple and easy way to build groups of nav links with optional headers. They're best used in sidebars like the Finder in OS X.

Example nav list

Take a list of links and add class="nav nav-list":

<ul class="nav nav-list">
  <li class="nav-header">List header</li>
  <li class="active"><a href="#">Home</a></li>
  <li><a href="#">Library</a></li>
  ...
</ul>

Note For nesting within a nav list, include class="nav nav-list" on any nested <ul>.

Horizontal dividers

Add a horizontal divider by creating an empty list item with the class .divider, like so:

<ul class="nav nav-list">
  ...
  <li class="divider"></li>
  ...
</ul>

Tabbable nav

Bring your tabs to life with a simple plugin to toggle between content via tabs. Bootstrap integrates tabbable tabs in four styles: top (default), right, bottom, and left.

Tabbable example

To make tabs tabbable, create a .tab-pane with unique ID for every tab and wrap them in .tab-content.

I'm in Section 1.

Howdy, I'm in Section 2.

What up girl, this is Section 3.

<div class="tabbable"> <!-- Only required for left/right tabs -->
  <ul class="nav nav-tabs">
    <li class="active"><a href="#tab1" data-toggle="tab">Section 1</a></li>
    <li><a href="#tab2" data-toggle="tab">Section 2</a></li>
  </ul>
  <div class="tab-content">
    <div class="tab-pane active" id="tab1">
      <p>I'm in Section 1.</p>
    </div>
    <div class="tab-pane" id="tab2">
      <p>Howdy, I'm in Section 2.</p>
    </div>
  </div>
</div>

Fade in tabs

To make tabs fade in, add .fade to each .tab-pane.

Requires jQuery plugin

All tabbable tabs are powered by our lightweight jQuery plugin. Read more about how to bring tabbable tabs to life on the JavaScript docs page.

Tabbable in any direction

Tabs on the bottom

Flip the order of the HTML and add a class to put tabs on the bottom.

I'm in Section A.

Howdy, I'm in Section B.

What up girl, this is Section C.

<div class="tabbable tabs-below">
  <div class="tab-content">
    ...
  </div>
  <ul class="nav nav-tabs">
    ...
  </ul>
</div>

Tabs on the left

Swap the class to put tabs on the left.

I'm in Section A.

Howdy, I'm in Section B.

What up girl, this is Section C.

<div class="tabbable tabs-left">
  <ul class="nav nav-tabs">
    ...
  </ul>
  <div class="tab-content">
    ...
  </div>
</div>

Tabs on the right

Swap the class to put tabs on the right.

I'm in Section A.

Howdy, I'm in Section B.

What up girl, this is Section C.

<div class="tabbable tabs-right">
  <ul class="nav nav-tabs">
    ...
  </ul>
  <div class="tab-content">
    ...
  </div>
</div>

Basic navbar

To start, navbars are static (not fixed to the top) and include support for a project name and basic navigation. Place one anywhere within a .container, which sets the width of your site and content.

<div class="navbar">
  <div class="navbar-inner">
    <a class="brand" href="#">Title</a>
    <ul class="nav">
      <li class="active"><a href="#">Home</a></li>
      <li><a href="#">Link</a></li>
      <li><a href="#">Link</a></li>
    </ul>
  </div>
</div>

Navbar components

Brand

A simple link to show your brand or project name only requires an anchor tag.

<a class="brand" href="#">Project name</a>

Nav links

Nav items are simple to add via unordered lists.

<ul class="nav">
  <li class="active">
    <a href="#">Home</a>
  </li>
  <li><a href="#">Link</a></li>
  <li><a href="#">Link</a></li>
</ul>

You can easily add dividers to your nav links with an empty list item and a simple class. Just add this between links:

<ul class="nav">
  ...
  <li class="divider-vertical"></li>
  ...
</ul>

Forms

To properly style and position a form within the navbar, add the appropriate classes as shown below. For a default form, include .navbar-form and either .pull-left or .pull-right to properly align it.

<form class="navbar-form pull-left">
  <input type="text" class="span2">
  <button type="submit" class="btn">Submit</button>
</form>

Search form

For a more customized search form, add .navbar-search to the form and .search-query to the input for specialized styles in the navbar.

<form class="navbar-search pull-left">
  <input type="text" class="search-query" placeholder="Search">
</form>

Component alignment

Align nav links, search form, or text, use the .pull-left or .pull-right utility classes. Both classes will add a CSS float in the specified direction.

Using dropdowns

Add dropdowns and dropups to the nav with a bit of markup and the dropdowns JavaScript plugin.

<ul class="nav">
  <li class="dropdown">
    <a href="#" class="dropdown-toggle" data-toggle="dropdown">
      Account
      <b class="caret"></b>
    </a>
    <ul class="dropdown-menu">
      ...
    </ul>
  </li>
</ul>

Visit the JavaScript dropdowns documentation for more markup and information on calling dropdowns.

Text

Wrap strings of text in an element with .navbar-text, usually on a <p> tag for proper leading and color.

Optional display variations

Fix the navbar to the top or bottom of the viewport with an additional class on the outermost div, .navbar.

Fixed to top

Add .navbar-fixed-top and remember to account for the hidden area underneath it by adding at least 40px padding to the <body>. Be sure to add this after the core Bootstrap CSS and before the optional responsive CSS.

<div class="navbar navbar-fixed-top">
  ...
</div>

Fixed to bottom

Add .navbar-fixed-bottom instead.

<div class="navbar navbar-fixed-bottom">
  ...
</div>

Static top navbar

Create a full-width navbar that scrolls away with the page by adding .navbar-static-top. Unlike the .navbar-fixed-top class, you do not need to change any padding on the body.

<div class="navbar navbar-static-top">
  ...
</div>

Responsive navbar

To implement a collapsing responsive navbar, wrap your navbar content in a containing div, .nav-collapse.collapse, and add the navbar toggle button, .btn-navbar.

<div class="navbar">
  <div class="navbar-inner">
    <div class="container">

      <!-- .btn-navbar is used as the toggle for collapsed navbar content -->
      <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </a>

      <!-- Be sure to leave the brand out there if you want it shown -->
      <a class="brand" href="#">Project name</a>

      <!-- Everything you want hidden at 940px or less, place within here -->
      <div class="nav-collapse collapse">
        <!-- .nav, .navbar-search, .navbar-form, etc -->
      </div>

    </div>
  </div>
</div>

Heads up! The responsive navbar requires the collapse plugin and responsive Bootstrap CSS file.

Inverted variation

Modify the look of the navbar by adding .navbar-inverse.

<div class="navbar navbar-inverse">
  ...
</div>

Examples

A single example shown as it might be displayed across multiple pages.

<ul class="breadcrumb">
  <li><a href="#">Home</a> <span class="divider">/</span></li>
  <li><a href="#">Library</a> <span class="divider">/</span></li>
  <li class="active">Data</li>
</ul>

Standard pagination

Simple pagination inspired by Rdio, great for apps and search results. The large block is hard to miss, easily scalable, and provides large click areas.

<div class="pagination">
  <ul>
    <li><a href="#">Prev</a></li>
    <li><a href="#">1</a></li>
    <li><a href="#">2</a></li>
    <li><a href="#">3</a></li>
    <li><a href="#">4</a></li>
    <li><a href="#">5</a></li>
    <li><a href="#">Next</a></li>
  </ul>
</div>

Options

Disabled and active states

Links are customizable for different circumstances. Use .disabled for unclickable links and .active to indicate the current page.

<div class="pagination">
  <ul>
    <li class="disabled"><a href="#">&laquo;</a></li>
    <li class="active"><a href="#">1</a></li>
    ...
  </ul>
</div>

You can optionally swap out active or disabled anchors for spans to remove click functionality while retaining intended styles.

<div class="pagination">
  <ul>
    <li class="disabled"><span>&laquo;</span></li>
    <li class="active"><span>1</span></li>
    ...
  </ul>
</div>

Sizes

Fancy larger or smaller pagination? Add .pagination-large, .pagination-small, or .pagination-mini for additional sizes.

<div class="pagination pagination-large">
  <ul>
    ...
  </ul>
</div>
<div class="pagination">
  <ul>
    ...
  </ul>
</div>
<div class="pagination pagination-small">
  <ul>
    ...
  </ul>
</div>
<div class="pagination pagination-mini">
  <ul>
    ...
  </ul>
</div>

Alignment

Add one of two optional classes to change the alignment of pagination links: .pagination-centered and .pagination-right.

<div class="pagination pagination-centered">
  ...
</div>

<div class="pagination pagination-right">
  ...
</div>

Pager

Quick previous and next links for simple pagination implementations with light markup and styles. It's great for simple sites like blogs or magazines.

Default example

By default, the pager centers links.

<ul class="pager">
  <li><a href="#">Previous</a></li>
  <li><a href="#">Next</a></li>
</ul>

Aligned links

Alternatively, you can align each link to the sides:

<ul class="pager">
  <li class="previous">
    <a href="#">&larr; Older</a>
  </li>
  <li class="next">
    <a href="#">Newer &rarr;</a>
  </li>
</ul>

Optional disabled state

Pager links also use the general .disabled utility class from the pagination.

<ul class="pager">
  <li class="previous disabled">
    <a href="#">&larr; Older</a>
  </li>
  ...
</ul>

Easily collapsible

For easy implementation, labels and badges will simply collapse (via CSS's :empty selector) when no content exists within.

Hero unit

A lightweight, flexible component to showcase key content on your site. It works well on marketing and content-heavy sites.

Hello, world!

This is a simple hero unit, a simple jumbotron-style component for calling extra attention to featured content or information.

Learn more

<div class="hero-unit">
  <h1>Heading</h1>
  <p>Tagline</p>
  <p>
    <a class="btn btn-primary btn-large">
      Learn more
    </a>
  </p>
</div>

Page header

A simple shell for an h1 to appropriately space out and segment sections of content on a page. It can utilize the h1's default small, element as well most other components (with additional styles).

<div class="page-header">
  <h1>Example page header <small>Subtext for header</small></h1>
</div>

Default thumbnails

By default, Bootstrap's thumbnails are designed to showcase linked images with minimal required markup.

Highly customizable

With a bit of extra markup, it's possible to add any kind of HTML content like headings, paragraphs, or buttons into thumbnails.

Thumbnail label

Cras justo odio, dapibus ac facilisis in, egestas eget quam. Donec id elit non mi porta gravida at eget metus. Nullam id dolor id nibh ultricies vehicula ut id elit.

Action Action
Thumbnail label

Cras justo odio, dapibus ac facilisis in, egestas eget quam. Donec id elit non mi porta gravida at eget metus. Nullam id dolor id nibh ultricies vehicula ut id elit.

Why use thumbnails

Thumbnails (previously .media-grid up until v1.4) are great for grids of photos or videos, image search results, retail products, portfolios, and much more. They can be links or static content.

Simple, flexible markup

Thumbnail markup is simple—a ul with any number of li elements is all that is required. It's also super flexible, allowing for any type of content with just a bit more markup to wrap your contents.

Uses grid column sizes

Lastly, the thumbnails component uses existing grid system classes—like .span2 or .span3—for control of thumbnail dimensions.

Markup

As mentioned previously, the required markup for thumbnails is light and straightforward. Here's a look at the default setup for linked images:

<ul class="thumbnails">
  <li class="span4">
    <a href="#" class="thumbnail">
      <img data-src="holder.js/300x200" alt="">
    </a>
  </li>
  ...
</ul>

For custom HTML content in thumbnails, the markup changes slightly. To allow block level content anywhere, we swap the <a> for a <div> like so:

<ul class="thumbnails">
  <li class="span4">
    <div class="thumbnail">
      <img data-src="holder.js/300x200" alt="">
      <h3>Thumbnail label</h3>
      <p>Thumbnail caption...</p>
    </div>
  </li>
  ...
</ul>

More examples

Explore all your options with the various grid classes available to you. You can also mix and match different sizes.

Default alert

Wrap any text and an optional dismiss button in .alert for a basic warning alert message.

Warning! Best check yo self, you're not looking too good.

<div class="alert">
  <button type="button" class="close" data-dismiss="alert">&times;</button>
  <strong>Warning!</strong> Best check yo self, you're not looking too good.
</div>

Dismiss buttons

Mobile Safari and Mobile Opera browsers, in addition to the data-dismiss="alert" attribute, require an href="#" for the dismissal of alerts when using an <a> tag.

<a href="#" class="close" data-dismiss="alert">&times;</a>

Alternatively, you may use a <button> element with the data attribute, which we have opted to do for our docs. When using <button>, you must include type="button" or your forms may not submit.

<button type="button" class="close" data-dismiss="alert">&times;</button>

Dismiss alerts via JavaScript

Use the alerts jQuery plugin for quick and easy dismissal of alerts.

Options

For longer messages, increase the padding on the top and bottom of the alert wrapper by adding .alert-block.

Warning!

Best check yo self, you're not looking too good. Nulla vitae elit libero, a pharetra augue. Praesent commodo cursus magna, vel scelerisque nisl consectetur et.

<div class="alert alert-block">
  <button type="button" class="close" data-dismiss="alert">&times;</button>
  <h4>Warning!</h4>
  Best check yo self, you're not...
</div>

Contextual alternatives

Add optional classes to change an alert's connotation.

Error or danger

Oh snap! Change a few things up and try submitting again.

<div class="alert alert-error">
  ...
</div>

Success

Well done! You successfully read this important alert message.

<div class="alert alert-success">
  ...
</div>

Information

Heads up! This alert needs your attention, but it's not super important.

<div class="alert alert-info">
  ...
</div>

Examples and markup

Basic

Default progress bar with a vertical gradient.

<div class="progress">
  <div class="bar" style="width: 60%;"></div>
</div>

Striped

Uses a gradient to create a striped effect. Not available in IE7-8.

<div class="progress progress-striped">
  <div class="bar" style="width: 20%;"></div>
</div>

Animated

Add .active to .progress-striped to animate the stripes right to left. Not available in all versions of IE.

<div class="progress progress-striped active">
  <div class="bar" style="width: 40%;"></div>
</div>

Stacked

Place multiple bars into the same .progress to stack them.

<div class="progress">
  <div class="bar bar-success" style="width: 35%;"></div>
  <div class="bar bar-warning" style="width: 20%;"></div>
  <div class="bar bar-danger" style="width: 10%;"></div>
</div>

Options

Additional colors

Progress bars use some of the same button and alert classes for consistent styles.

<div class="progress progress-info">
  <div class="bar" style="width: 20%"></div>
</div>
<div class="progress progress-success">
  <div class="bar" style="width: 40%"></div>
</div>
<div class="progress progress-warning">
  <div class="bar" style="width: 60%"></div>
</div>
<div class="progress progress-danger">
  <div class="bar" style="width: 80%"></div>
</div>

Striped bars

Similar to the solid colors, we have varied striped progress bars.

<div class="progress progress-info progress-striped">
  <div class="bar" style="width: 20%"></div>
</div>
<div class="progress progress-success progress-striped">
  <div class="bar" style="width: 40%"></div>
</div>
<div class="progress progress-warning progress-striped">
  <div class="bar" style="width: 60%"></div>
</div>
<div class="progress progress-danger progress-striped">
  <div class="bar" style="width: 80%"></div>
</div>

Browser support

Progress bars use CSS3 gradients, transitions, and animations to achieve all their effects. These features are not supported in IE7-9 or older versions of Firefox.

Versions earlier than Internet Explorer 10 and Opera 12 do not support animations.

Abstract object styles for building various types of components (like blog comments, Tweets, etc) that feature a left- or right-aligned image alongside textual content.

Default example

The default media allow to float a media object (images, video, audio) to the left or right of a content block.

Media heading

Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin commodo. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.

Media heading

<div class="media">
  <a class="pull-left" href="#">
    <img class="media-object" data-src="holder.js/64x64">
  </a>
  <div class="media-body">
    <h4 class="media-heading">Media heading</h4>
    ...

    <!-- Nested media object -->
    <div class="media">
      ...
    </div>
  </div>
</div>

Media list

With a bit of extra markup, you can use media inside list (useful for comment threads or articles lists).

Media heading

  ...
</div>

Close icon

Use the generic close icon for dismissing content like modals and alerts.

<button class="close">&times;</button>

iOS devices require an href="#" for click events if you would rather use an anchor.

.pull-left

Float an element left

class="pull-left"

Bootstrap CSS

Headings

All HTML headings, <h1> through <h6> are available.

h1. Heading 1

h2. Heading 2

h3. Heading 3

h4. Heading 4

h5. Heading 5

h6. Heading 6

Body copy

Bootstrap's global default font-size is 14px, with a line-height of 20px. This is applied to the <body> and all paragraphs. In addition, <p> (paragraphs) receive a bottom margin of half their 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: @baseFontSize and @baseLineHeight. 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.

Emphasis

Make use of HTML's default emphasis tags with lightweight styles.

`<small>`

For de-emphasizing inline or blocks of text, use the small tag.

This line of text is meant to be treated as fine print.

<p>
  <small>This line of text is meant to be treated as fine print.</small>
</p>

Bold

For emphasizing a snippet of text with a heavier font-weight.

The following snippet of text is rendered as bold text.

<strong>rendered as bold text</strong>

Italics

For emphasizing a snippet of text with italics.

The following snippet of text is rendered as italicized text.

<em>rendered as italicized text</em>

Heads up! Feel free to use <b> and <i> in HTML5. <b> is meant to highlight words or phrases without conveying additional importance while <i> is mostly for voice, technical terms, etc.

Alignment classes

Easily realign text to components with text alignment classes.

Left aligned text.

Center aligned text.

Right aligned text.

<p class="text-left">Left aligned text.</p>
<p class="text-center">Center aligned text.</p>
<p class="text-right">Right aligned text.</p>

Emphasis classes

Convey meaning through color with a handful of emphasis utility classes.

Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.

Etiam porta sem malesuada magna mollis euismod.

Donec ullamcorper nulla non metus auctor fringilla.

Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis.

Duis mollis, est non commodo luctus, nisi erat porttitor ligula.

<p class="muted">Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.</p>
<p class="text-warning">Etiam porta sem malesuada magna mollis euismod.</p>
<p class="text-error">Donec ullamcorper nulla non metus auctor fringilla.</p>
<p class="text-info">Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis.</p>
<p class="text-success">Duis mollis, est non commodo luctus, nisi erat porttitor ligula.</p>

Abbreviations

Stylized implementation of HTML's <abbr> element for abbreviations and acronyms to show the expanded version on hover. Abbreviations with a title attribute have a light dotted bottom border and a help cursor on hover, providing additional context on hover.

`<abbr>`

For expanded text on long hover of an abbreviation, include the title attribute.

An abbreviation of the word attribute is attr.

<abbr title="attribute">attr</abbr>

`<abbr class="initialism">`

Add .initialism to an abbreviation for a slightly smaller font-size.

HTML is the best thing since sliced bread.

<abbr title="HyperText Markup Language" class="initialism">HTML</abbr>

Addresses

Present contact information for the nearest ancestor or the entire body of work.

`<address>`

Preserve formatting by ending all lines with <br>.

Twitter, Inc.

Blockquotes

For quoting blocks of content from another source within your document.

Default blockquote

Wrap <blockquote> around any HTML as the quote. For straight quotes we recommend a <p>.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.

<blockquote>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
</blockquote>

Blockquote options

Style and content changes for simple variations on a standard blockquote.

Naming a source

Add <small> tag for identifying the source. Wrap the name of the source work in <cite>.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.
Someone famous in Source Title

<blockquote>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
  <small>Someone famous <cite title="Source Title">Source Title</cite></small>
</blockquote>

Alternate displays

Use .pull-right for a floated, right-aligned blockquote.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.
Someone famous in Source Title

<blockquote class="pull-right">
  ...
</blockquote>

Lists

Unordered

A list of items in which the order does not explicitly matter.

Lorem ipsum dolor sit amet
Consectetur adipiscing elit
Integer molestie lorem at massa
Facilisis in pretium nisl aliquet
Nulla volutpat aliquam velit
- Phasellus iaculis neque
- Purus sodales ultricies
- Vestibulum laoreet porttitor sem
- Ac tristique libero volutpat at
Faucibus porta lacus fringilla vel
Aenean sit amet erat nunc
Eget porttitor lorem

<ul>
  <li>...</li>
</ul>

Ordered

A list of items in which the order does explicitly matter.

Lorem ipsum dolor sit amet
Consectetur adipiscing elit
Integer molestie lorem at massa
Facilisis in pretium nisl aliquet
Nulla volutpat aliquam velit
Faucibus porta lacus fringilla vel
Aenean sit amet erat nunc
Eget porttitor lorem

<ol>
  <li>...</li>
</ol>

Unstyled

Remove the default list-style and left padding on list items (immediate children only).

Lorem ipsum dolor sit amet
Consectetur adipiscing elit
Integer molestie lorem at massa
Facilisis in pretium nisl aliquet
Nulla volutpat aliquam velit
- Phasellus iaculis neque
- Purus sodales ultricies
- Vestibulum laoreet porttitor sem
- Ac tristique libero volutpat at
Faucibus porta lacus fringilla vel
Aenean sit amet erat nunc
Eget porttitor lorem

<ul class="unstyled">
  <li>...</li>
</ul>

Inline

Place all list items on a single line with inline-block and some light padding.

Lorem ipsum
Phasellus iaculis
Nulla volutpat

<ul class="inline">
  <li>...</li>
</ul>

Description

A list of terms with their associated descriptions.

Description lists: A description list is perfect for defining terms.
Euismod: Vestibulum id ligula porta felis euismod semper eget lacinia odio sem nec elit.; Donec id elit non mi porta gravida at eget metus.
Malesuada porta: Etiam porta sem malesuada magna mollis euismod.

<dl>
  <dt>...</dt>
  <dd>...</dd>
</dl>

Horizontal description

Make terms and descriptions in <dl> line up side-by-side.

Description lists: A description list is perfect for defining terms.
Euismod: Vestibulum id ligula porta felis euismod semper eget lacinia odio sem nec elit.; Donec id elit non mi porta gravida at eget metus.
Malesuada porta: Etiam porta sem malesuada magna mollis euismod.
Felis euismod semper eget lacinia: Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.

<dl class="dl-horizontal">
  <dt>...</dt>
  <dd>...</dd>
</dl>

Heads up! Horizontal description lists will truncate terms that are too long to fit in the left column fix text-overflow. In narrower viewports, they will change to the default stacked layout.

Inline

Wrap inline snippets of code with <code>.

For example, <section> should be wrapped as inline.

For example, <code>&lt;section&gt;</code> should be wrapped as inline.

Basic block

Use <pre> for multiple lines of code. Be sure to escape any angle brackets in the code for proper rendering.

<p>Sample text here...</p>

<pre>
  &lt;p&gt;Sample text here...&lt;/p&gt;
</pre>

Heads up! Be sure to keep code within <pre> tags as close to the left as possible; it will render all tabs.

You may optionally add the .pre-scrollable class which will set a max-height of 350px and provide a y-axis scrollbar.

Default styles

For basic styling—light padding and only horizontal dividers—add the base class .table to any <table>.

#	First Name	Last Name	Username
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry	the Bird	@twitter

<table class="table">
  …
</table>

Optional classes

Add any of the following classes to the .table base class.

`.table-striped`

Adds zebra-striping to any table row within the <tbody> via the :nth-child CSS selector (not available in IE7-8).

`.table-condensed`

Makes 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		@twitter

<table class="table table-condensed">
  …
</table>

Optional row classes

Use contextual classes to color table rows.

Class	Description

Tag	Description
`<table>`	Wrapping element for displaying data in a tabular format
`<thead>`	Container element for table header rows (`<tr>`) to label table columns
`<tbody>`	Container element for table rows (`<tr>`) in the body of the table

    </tr>
  </thead>
  <tbody>
    <tr>
      <td>...</td>
      <td>...</td>
    </tr>
  </tbody>
</table>

Default styles

Individual form controls receive styling, but without any required base class on the <form> or large changes in markup. Results in stacked, left-aligned labels on top of form controls.

<form>
  <fieldset>
    <legend>Legend</legend>
    <label>Label name</label>
    <input type="text" placeholder="Type something…">
    <span class="help-block">Example block-level help text here.</span>
    <label class="checkbox">
      <input type="checkbox"> Check me out
    </label>
    <button type="submit" class="btn">Submit</button>
  </fieldset>
</form>

Optional layouts

Included with Bootstrap are three optional form layouts for common use cases.

Search form

Add .form-search to the form and .search-query to the <input> for an extra-rounded text input.

<form class="form-search">
  <input type="text" class="input-medium search-query">
  <button type="submit" class="btn">Search</button>
</form>

Inline form

Add .form-inline for left-aligned labels and inline-block controls for a compact layout.

<form class="form-inline">
  <input type="text" class="input-small" placeholder="Email">
  <input type="password" class="input-small" placeholder="Password">
  <label class="checkbox">
    <input type="checkbox"> Remember me
  </label>
  <button type="submit" class="btn">Sign in</button>
</form>

Horizontal form

Right align labels and float them to the left to make them appear on the same line as controls. Requires the most markup changes from a default form:

Add .form-horizontal to the form
Wrap labels and controls in .control-group
Add .control-label to the label
Wrap any associated controls in .controls for proper alignment

<form class="form-horizontal">
  <div class="control-group">
    <label class="control-label" for="inputEmail">Email</label>
    <div class="controls">
      <input type="text" id="inputEmail" placeholder="Email">
    </div>
  </div>
  <div class="control-group">
    <label class="control-label" for="inputPassword">Password</label>
    <div class="controls">
      <input type="password" id="inputPassword" placeholder="Password">
    </div>
  </div>
  <div class="control-group">
    <div class="controls">
      <label class="checkbox">
        <input type="checkbox"> Remember me
      </label>
      <button type="submit" class="btn">Sign in</button>
    </div>
  </div>
</form>

Supported form 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.

Requires the use of a specified type at all times.

<input type="text" placeholder="Text input">

Textarea

Form control which supports multiple lines of text. Change rows attribute as necessary.

<textarea 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.

Default (stacked)

<label class="checkbox">
  <input type="checkbox" value="">
  Option one is this and that—be sure to include why it's great
</label>

<label class="radio">
  <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>
<label class="radio">
  <input type="radio" name="optionsRadios" id="optionsRadios2" value="option2">
  Option two can be something else and selecting it will deselect option one
</label>

Inline checkboxes

Add the .inline class to a series of checkboxes or radios for controls 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>

Selects

Use the default option or specify a multiple="multiple" to show multiple options at once.

<select>
  <option>1</option>
  <option>2</option>
  <option>3</option>
  <option>4</option>
  <option>5</option>
</select>

<select multiple="multiple">
  <option>1</option>
  <option>2</option>
  <option>3</option>
  <option>4</option>
  <option>5</option>
</select>

Extending form controls

Adding on top of existing browser controls, Bootstrap includes other useful form components.

Prepended and appended inputs

Add text or buttons before or after any text-based input. Do note that select elements are not supported here.

Default options

Wrap an .add-on and an input with one of two classes to prepend or append text to an input.

<div class="input-prepend">
  <span class="add-on">@</span>
  <input class="span2" id="prependedInput" type="text" placeholder="Username">
</div>
<div class="input-append">
  <input class="span2" id="appendedInput" type="text">
  <span class="add-on">.00</span>
</div>

Combined

Use both classes and two instances of .add-on to prepend and append an input.

<div class="input-prepend input-append">
  <span class="add-on">$</span>
  <input class="span2" id="appendedPrependedInput" type="text">
  <span class="add-on">.00</span>
</div>

Buttons instead of text

Instead of a <span> with text, use a .btn to attach a button (or two) to an input.

<div class="input-append">
  <input class="span2" id="appendedInputButton" type="text">
  <button class="btn" type="button">Go!</button>
</div>

<div class="input-append">
  <input class="span2" id="appendedInputButtons" type="text">
  <button class="btn" type="button">Search</button>
  <button class="btn" type="button">Options</button>
</div>

Button dropdowns

<div class="input-append">
  <input class="span2" id="appendedDropdownButton" type="text">
  <div class="btn-group">
    <button class="btn dropdown-toggle" data-toggle="dropdown">
      Action
      <span class="caret"></span>
    </button>
    <ul class="dropdown-menu">
      ...
    </ul>
  </div>
</div>

<div class="input-prepend">
  <div class="btn-group">
    <button class="btn dropdown-toggle" data-toggle="dropdown">
      Action
      <span class="caret"></span>
    </button>
    <ul class="dropdown-menu">
      ...
    </ul>
  </div>
  <input class="span2" id="prependedDropdownButton" type="text">
</div>

<div class="input-prepend input-append">
  <div class="btn-group">
    <button class="btn dropdown-toggle" data-toggle="dropdown">
      Action
      <span class="caret"></span>
    </button>
    <ul class="dropdown-menu">
      ...
    </ul>
  </div>
  <input class="span2" id="appendedPrependedDropdownButton" type="text">
  <div class="btn-group">
    <button class="btn dropdown-toggle" data-toggle="dropdown">
      Action
      <span class="caret"></span>
    </button>
    <ul class="dropdown-menu">
      ...
    </ul>
  </div>
</div>

Segmented dropdown groups

<form>
  <div class="input-prepend">
    <div class="btn-group">...</div>
    <input type="text">
  </div>
  <div class="input-append">
    <input type="text">
    <div class="btn-group">...</div>
  </div>
</form>

Search form

<form class="form-search">
  <div class="input-append">
    <input type="text" class="span2 search-query">
    <button type="submit" class="btn">Search</button>
  </div>
  <div class="input-prepend">
    <button type="submit" class="btn">Search</button>
    <input type="text" class="span2 search-query">
  </div>
</form>

Control sizing

Use relative sizing classes like .input-large or match your inputs to the grid column sizes using .span* classes.

Block level inputs

Make any <input> or <textarea> element behave like a block level element.

<input class="input-block-level" type="text" placeholder=".input-block-level">

Relative sizing

<input class="input-mini" type="text" placeholder=".input-mini">
<input class="input-small" type="text" placeholder=".input-small">
<input class="input-medium" type="text" placeholder=".input-medium">
<input class="input-large" type="text" placeholder=".input-large">
<input class="input-xlarge" type="text" placeholder=".input-xlarge">
<input class="input-xxlarge" type="text" placeholder=".input-xxlarge">

Heads up! In future versions, we'll be altering the use of these relative input classes to match our button sizes. For example, .input-large will increase the padding and font-size of an input.

Grid sizing

Use .span1 to .span12 for inputs that match the same sizes of the grid columns.

<input class="span1" type="text" placeholder=".span1">
<input class="span2" type="text" placeholder=".span2">
<input class="span3" type="text" placeholder=".span3">
<select class="span1">
  ...
</select>
<select class="span2">
  ...
</select>
<select class="span3">
  ...
</select>

For multiple grid inputs per line, use the .controls-row modifier class for proper spacing. It floats the inputs to collapse white-space, sets the proper margins, and clears the float.

<div class="controls">
  <input class="span5" type="text" placeholder=".span5">
</div>
<div class="controls controls-row">
  <input class="span4" type="text" placeholder=".span4">
  <input class="span1" type="text" placeholder=".span1">
</div>
...

Uneditable inputs

Present data in a form that's not editable without using actual form markup.

<span class="input-xlarge uneditable-input">Some value here</span>

Form actions

End a form with a group of actions (buttons). When placed within a .form-actions, the buttons will automatically indent to line up with the form controls.

<div class="form-actions">
  <button type="submit" class="btn btn-primary">Save changes</button>
  <button type="button" class="btn">Cancel</button>
</div>

Help text

Inline and block level support for help text that appears around form controls.

Inline help

<input type="text"><span class="help-inline">Inline help text</span>

Block help

<input type="text"><span class="help-block">A longer block of help text that breaks onto a new line and may extend beyond one line.</span>

Form control states

Provide feedback to users or visitors with basic feedback states on form controls and labels.

Input focus

We remove the default outline styles on some form controls and apply a box-shadow in its place for :focus.

<input class="input-xlarge" id="focusedInput" type="text" value="This is focused...">

Invalid inputs

Style inputs via default browser functionality with :invalid. Specify a type, add the required attribute if the field is not optional, and (if applicable) specify a pattern.

This is not available in versions of Internet Explorer 7-9 due to lack of support for CSS pseudo selectors.

<input class="span3" type="email" required>

Disabled inputs

Add the disabled attribute on an input to prevent user input and trigger a slightly different look.

<input class="input-xlarge" id="disabledInput" type="text" placeholder="Disabled input here..." disabled>

Validation states

Bootstrap includes validation styles for error, warning, info, and success messages. To use, add the appropriate class to the surrounding .control-group.

<div class="control-group warning">
  <label class="control-label" for="inputWarning">Input with warning</label>

Default buttons

Button styles can be applied to anything with the .btn class applied. However, typically you'll want to apply these to only <a> and <button> elements for the best rendering.

Button	class=""	Description
	`btn`	Standard gray button with gradient
	`btn btn-primary`	Provides extra visual weight and identifies the primary action in a set of buttons
	`btn btn-info`	Used as an alternative to the default styles
	`btn btn-success`	Indicates a successful or positive action
	`btn btn-warning`	Indicates caution should be taken with this action
	`btn btn-danger`	Indicates a dangerous or potentially negative action
	`btn btn-inverse`	Alternate dark gray button, not tied to a semantic action or use
	`btn btn-link`	Deemphasize a button by making it look like a link while maintaining button behavior

Cross browser compatibility

IE9 doesn't crop background gradients on rounded corners, so we remove it. Related, IE9 jankifies disabled button elements, rendering text gray with a nasty text-shadow that we cannot fix.

Button sizes

Fancy larger or smaller buttons? Add .btn-large, .btn-small, or .btn-mini for additional sizes.

<p>
  <button class="btn btn-large btn-primary" type="button">Large button</button>
  <button class="btn btn-large" type="button">Large button</button>
</p>
<p>
  <button class="btn btn-primary" type="button">Default button</button>
  <button class="btn" type="button">Default button</button>
</p>
<p>
  <button class="btn btn-small btn-primary" type="button">Small button</button>
  <button class="btn btn-small" type="button">Small button</button>
</p>
<p>
  <button class="btn btn-mini btn-primary" type="button">Mini button</button>
  <button class="btn btn-mini" type="button">Mini button</button>
</p>

Create block level buttons—those that span the full width of a parent— by adding .btn-block.

<button class="btn btn-large btn-block btn-primary" type="button">Block level button</button>
<button class="btn btn-large btn-block" type="button">Block level button</button>

Disabled state

Make buttons look unclickable by fading them back 50%.

Anchor element

Add the .disabled class to <a> buttons.

Primary link Link

<a href="#" class="btn btn-large btn-primary disabled">Primary link</a>
<a href="#" class="btn btn-large disabled">Link</a>

Heads up! We use .disabled as a utility class here, similar to the common .active class, so no prefix is required. Also, this class is only for aesthetic; you must use custom JavaScript to disable links here.

Button element

Add the disabled attribute to <button> buttons.

<button type="button" class="btn btn-large btn-primary disabled" disabled="disabled">Primary button</button>
<button type="button" class="btn btn-large" disabled>Button</button>

One class, multiple tags

Use the .btn class on an <a>, <button>, or <input> element.

<a class="btn" href="/">Link</a>
<button class="btn" type="submit">Button</button>
<input class="btn" type="button" value="Input">
<input class="btn" type="submit" value="Submit">

As a best practice, try to match the element for your context to ensure matching cross-browser rendering. If you have an input, use an <input type="submit"> for your button.

Add classes to an <img> element to easily style images in any project.

<img src="/....." class="img-rounded">
<img src="/....." class="img-circle">
<img src="/....." class="img-polaroid">

Heads up! .img-rounded and .img-circle do not work in IE7-8 due to lack of border-radius support.

Glyphicons attribution

Glyphicons Halflings are normally not available for free, but an arrangement between Bootstrap and the Glyphicons creators have made this possible at no cost to you as developers. As a thank you, we ask you to include an optional link back to Glyphicons whenever practical.

How to use

All icons require an <i> tag with a unique class, prefixed with icon-. To use, place the following code just about anywhere:

<i class="icon-search"></i>

There are also styles available for inverted (white) icons, made ready with one extra class. We will specifically enforce this class on hover and active states for nav and dropdown links.

<i class="icon-search icon-white"></i>

Heads up! When using beside strings of text, as in buttons or nav links, be sure to leave a space after the <i> tag for proper spacing.

Icon examples

Use them in buttons, button groups for a toolbar, navigation, or prepended form inputs.
