Default alert

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

<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.

<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>

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>

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

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

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).

<ul class="media-list">
  <li 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>
  </li>
</ul>

• 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;

  }
}
