Provide contextual feedback messages for typical user actions with the handful of available and flexible alert messages. For inline dismissal, use the [alerts jQuery plugin]({{ site.baseurl }}javascript/#alerts).

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.

{% example html %}

Well done! You successfully read this important alert message.

Heads up! This alert needs your attention, but it's not super important.

Warning! Better check yourself, you're not looking too good.

Oh snap! Change a few things up and try submitting again.

Dismissing

Build on any alert by adding an optional .alert-dismissible and close button.

{% example html %}

× Close Warning! Better check yourself, you're not looking too good.

Ensure proper behavior across all devices

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

Link color

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

{% example html %}
