            Components components, javascript plugins

            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">1</button>
              <button class="btn">2</button>
              <button class="btn">3</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>
            

            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="#">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="#">Prev</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>Prev</span></li>
                <li class="active"><span>1</span></li>
                ...
              </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>
            

            Labels

            Labels Markup
            Default <span class="label">Default</span>
            Success <span class="label label-success">Success</span>
            Warning <span class="label label-warning">Warning</span>
            Important <span class="label label-important">Important</span>
            Info <span class="label label-info">Info</span>
            Inverse <span class="label label-inverse">Inverse</span>

            Badges

            Name Example Markup
            Default 1 <span class="badge">1</span>
            Success 2 <span class="badge badge-success">2</span>
            Warning 4 <span class="badge badge-warning">4</span>
            Important 6 <span class="badge badge-important">6</span>
            Info 8 <span class="badge badge-info">8</span>
            Inverse 10 <span class="badge badge-inverse">10</span>

            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.

            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 src="http://placehold.it/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 src="http://placehold.it/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">×</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">×</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">×</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">×</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.

            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">
              ...

            Look, I'm in a well!

            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 rather use an anchor.

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