bootstrap alerts


Bootstrap provides an easy way to create predefined alert messages. Alerts are created with the alert class followed by one of the four contextual classes alert-success, alert-info, alert-warning or alert-danger.

Success! Indicates a successful or positive action.
Info! Indicates a neutral informative change or action.
Warning! Indicates a warning that might need attention.
Danger! Indicates a dangerous or potentially negative action.
<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>

You can add the alert-link class to any links inside the alert box to create matching colored links.

Success! 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>

To close the alert message, add alert-dismissable class to the alert container and class="close" and data-dismiss="alert" to a link or a button element.

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

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

× Success! Indicates a successful or positive action.
<div class="alert alert-success alert-dismissable fade in">
  <a href="#" class="close" data-dismiss="alert" aria-label="close">×</a>
  <strong>Success!</strong> Indicates a successful or positive action.
</div>
