          Use button groups to join multiple buttons together as one composite component. Build them with a series of <a> or <button> elements.

          We recommend the following guidelines for using button groups and toolbars:

          • Always use the same element in a single button group, <a> or <button>.
          • Don't mix buttons of different colors in the same button group.
          • Use icons in addition to or instead of text, but be sure include alt and title text where appropriate.

          Related Button groups with dropdowns (see below) should be called out separately and always include a dropdown caret to indicate intended behavior.

          Here's how the HTML looks for a standard button group built with anchor tag buttons:

          <div class="btn-group">
            <button class="btn">1</button>
            <button class="btn">2</button>
            <button class="btn">3</button>
          </div>
          

          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>
          

          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.

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

          Similar to a button group, our markup uses regular button markup, but with a handful of additions to refine the style and support Bootstrap's dropdown jQuery plugin.

          <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>
          

          Button dropdowns work at any size. your button sizes to .btn-large, .btn-small, or .btn-mini.

          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.

          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.

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

          <div class="btn-group">
            ...
            <ul class="dropdown-menu pull-right">
              <!-- dropdown menu links -->
            </ul>
          </div>
          

          We expand on the normal button dropdowns to provide a second button action that operates as a separate dropdown trigger.

          <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>
          

          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>
          

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

          Links are customizable and work in a number of circumstances with the right class. .disabled for unclickable links and .active for current page.

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

          The default pagination component is flexible and works in a number of variations.

          Wrapped in a <div>, pagination is just a <ul>.

          <div class="pagination">
            <ul>
              <li><a href="#">Prev</a></li>
              <li class="active">
                <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>
          

          Pager For quick previous and next links

          The pager component is a set of links for simple pagination implementations with light markup and even lighter styles. It's great for simple sites like blogs or magazines.

          真钱网页买球网电子游艺

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

          By default, the pager centers links.

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

          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>
          
          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 are small, simple components for displaying an indicator or count of some sort. They're commonly found in email clients like Mail.app or on mobile apps for push notifications.

          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>

          Bootstrap provides a lightweight, flexible component called a hero unit to showcase content on your site. It works well on marketing and content-heavy sites.

          Wrap your content in a div like so:

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

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

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

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

          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.

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


          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="span3">
              <a href="#" class="thumbnail">
                <img src="http://placehold.it/260x180" 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="span3">
              <div class="thumbnail">
                <img src="http://placehold.it/260x180" alt="">
                <h5>Thumbnail label</h5>
                <p>Thumbnail caption right here...</p>
              </div>
            </li>
            ...
          </ul>
          

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

          With Bootstrap 2, we've simplified the base class: .alert instead of .alert-message. We've also reduced the minimum required markup—no <p> is required by default, just the outer <div>.

          For a more durable component with less code, we've removed the differentiating look for block alerts, messages that come with more padding and typically more text. The class also has changed to .alert-block.


          Bootstrap comes with a great jQuery plugin that supports alert messages, making dismissing them quick and easy.

          Get the plugin »

          Wrap your message and an optional close icon in a div with simple class.

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

          Heads up! iOS devices require an href="#" for the dismissal of alerts. Be sure to include it and the data attribute for anchor close icons. 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.

          Easily extend the standard alert message with two optional classes: .alert-block for more padding and text controls and .alert-heading for a matching heading.

          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.

            <a class="close" data-dismiss="alert" href="#">×</a>
            <h4 class="alert-heading">Warning!</h4>
            Best check yo self, you're not...
          </div>
          

          Contextual alternatives Add optional classes to change an alert's connotation

          Oh snap! Change a few things up and try submitting again.
          <div class="alert alert-error">
            ...
          </div>
          

          Well done! You successfully read this important alert message.
          <div class="alert alert-success">
            ...
          </div>
          

          Heads up! This alert needs your attention, but it's not super important.
          <div class="alert alert-info">
            ...
          </div>
          

          Default progress bar with a vertical gradient.

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

          Uses a gradient to create a striped effect (no IE).

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

          Takes the striped example and animates it (no IE).

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

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

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

          Progress bars use CSS3 transitions, so if you dynamically adjust the width via javascript, it will smoothly resize.

          If you use the .active class, your .progress-striped progress bars will animate the stripes left to right.

          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.

          Opera and IE do not support animations at this time.

          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>
          

          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>
