Provide contextual feedback messages for typical user actions with the handful of available and flexible alert messages.


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.

{% highlight html %} {% endhighlight %}

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.

{% highlight html %} {% endhighlight %}

Ensure proper behavior across all devices

Be sure to use the <button> element with the data-dismiss="alert" data attribute.

Use the .alert-link utility class to quickly provide matching colored links within any alert.

{% highlight html %} {% endhighlight %}
