Alerts

Bootstrap provides an easy way to create predefined alert messages.

Default markup

<div class="alert alert-success" role="alert">
   This is a success alert — check it out!
</div>
<div class="alert alert-info" role="alert">
   This is a info alert — check it out!
</div>
<div class="alert alert-warning" role="alert">
   This is a warning alert — check it out!
</div>
<div class="alert alert-danger" role="alert">
   This is a danger alert — check it out!
</div>

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

<div class="alert alert-success" role="alert">
   This is a success alert — <a href="#" class="alert-link">check it out</a>!
</div>
<div class="alert alert-info" role="alert">
   This is a info alert — <a href="#" class="alert-link">check it out</a>!
</div>
<div class="alert alert-warning" role="alert">
   This is a warning alert — <a href="#" class="alert-link">check it out</a>!
</div>
<div class="alert alert-danger" role="alert">
   This is a danger alert — <a href="#" class="alert-link">check it out</a>!
</div>

Dismissible Alerts

<div class="alert alert-success alert-dismissible" role="alert">
   This is a success alert — check it out!
   <a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a>
</div>
<div class="alert alert-info alert-dismissible" role="alert">
   This is a info alert — check it out!
   <a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a>
</div>
<div class="alert alert-warning alert-dismissible" role="alert">
   This is a warning alert — check it out!
   <a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a>
</div>
<div class="alert alert-danger alert-dismissible" role="alert">
   This is a danger alert — check it out!
   <a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a>
</div>
