Alerts ( Styles for success, warning, and error messages )

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>
    

Progress bars For loading, redirecting, or action status

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.


Media object

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.

64*64

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.

<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).

Miscellaneous Lightweight utility components

  • 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;
        }
      }
