This page demonstrates the available components in this template.

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.

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.

Button Dropdowns

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.

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>

Navs

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.

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.

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>

Navbar

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.

<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>

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>

Inverted variation

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

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

Typographic Components

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.

<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>

Thumbnails

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.

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 src="https://placekitten.com/300/200" 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 src="https://placekitten.com/300/200" alt="">
      <h4>Thumbnail label</h4>
      <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.

Alerts

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>

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>
  <h5>Warning!</h5>
  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>

Miscelaneous

Wells

Use the well as a simple effect on an element to give it an inset effect.

Look, I'm in a well!

<div class="well">
  ...
</div>

Optional classes

Control padding and rounded corners with two optional modifier classes.

Look, I'm in a well!

<div class="well well-large">
  ...
</div>

Look, I'm in a well!

<div class="well well-small">
  ...
</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.

<a class="close" href="#">&times;</a>

Helper classes

Simple, focused classes for small display or behavior tweaks.

.pull-left

Float an element left

class="pull-left"

.pull-left {
  float: left;
}

.pull-right

Float an element right

class="pull-right"

.pull-right {
  float: right;
}

.muted

Change an element's color to #999

class="muted"

.muted {
  color: #999;
}

.clearfix

Clear the float on any element

class="clearfix"

.clearfix {
  *zoom: 1;
  &:before,
  &:after {
    display: table;
    content: "";
  }
  &:after {
    clear: both;
  }
}
