Bootstrap Alerts

Alerts

Bootstrap provides an easy way to create predefined alert messages:

×Success! This alert box indicates a successful or positive action.

×Info! This alert box indicates a neutral informative change or action.

×Warning! This alert box indicates a warning that might need attention.

×Danger! This alert box indicates a dangerous or potentially negative action.

Alerts are created with the .alert class, followed by one of the four contextual classes .alert-success, .alert-info, .alert-warning or .alert-danger:

Example:

<div class="alert alert-success">
  <strong>Success!</strong> Indicates a successful or positive action.
</div>

<div class="alert alert-info">
  <strong>Info!</strong> Indicates a neutral informative change or action.
</div>

<div class="alert alert-warning">
  <strong>Warning!</strong> Indicates a warning that might need attention.
</div>

<div class="alert alert-danger">
  <strong>Danger!</strong> Indicates a dangerous or potentially negative action.
</div>

Alert Links

Add the alert-link class to any links inside the alert box to create "matching colored links":

Success! You should read this message.

Info! You should read this message.

Warning! You should read this message.

Danger! You should read this message.

<div class="alert alert-success">
  <strong>Success!</strong> You should <a href="#" class="alert-link">read this message</a>.
</div>

Closing Alerts

×Click on the "x" symbol to the right to close me.

To close the alert message, add a .alert-dismissible class to the alert container. Then add class="close" and data-dismiss="alert" to a link or a button element (when you click on this the alert box will disappear).

<div class="alert alert-success alert-dismissible">
  <a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a>
  <strong>Success!</strong> Indicates a successful or positive action.
</div>

Animated Alerts

×Click on the "x" symbol to the right to close me. I will "fade" out.

The .fade and .in classes adds a fading effect when closing the alert message:

<div class="alert alert-danger fade in">
