Provide contextual feedback messages for typical user actions with the handful of available and flexible alert messages.
Examples
Wrap any text and an optional dismiss button in .alert
and one of the four contextual classes (e.g., .alert-success
) for basic alert messages.
No default class
Alerts don't have default classes, only base and modifier classes. A default gray alert doesn't make too much sense, so you're required to specify a type via contextual class. Choose from success, info, warning, or danger.
<div class="alert alert-success" role="alert">...</div>
<div class="alert alert-info" role="alert">...</div>
<div class="alert alert-warning" role="alert">...</div>
<div class="alert alert-danger" role="alert">...</div>
Dismissible alerts
Build on any alert by adding an optional .alert-dismissible
and close button.
Requires JavaScript alert plugin
For fully functioning, dismissible alerts, you must use the alerts JavaScript plugin.
<div class="alert alert-warning alert-dismissible" role="alert">
<button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">×</span></button>
<strong>Warning!</strong> Better check yourself, you're not looking too good.
</div>
Ensure proper behavior across all devices
Be sure to use the <button>
element with the data-dismiss="alert"
data attribute.
Links in alerts
Use the .alert-link
utility class to quickly provide matching colored links within any alert.
<div class="alert alert-success" role="alert">
<a href="#" class="alert-link">...</a>
</div>
<div class="alert alert-info" role="alert">
<a href="#" class="alert-link">...</a>
</div>
<div class="alert alert-warning" role="alert">
<a href="#" class="alert-link">...</a>
</div>
<div class="alert alert-danger" role="alert">
<a href="#" class="alert-link">...</a>
</div>
