Alerts

Provide contextual feedback messages for typical user actions with the handful of available and flexible alert messages. Read the Official Bootstrap Documentation for a full list of instructions and other options.


Basic example

Alerts are available for any length of text, as well as an optional dismiss button. For proper styling, use one of the eight required contextual classes (e.g., .alert-success).

<div class="alert alert-primary" role="alert">
  A simple primary alert—check it out!
</div>
<div class="alert alert-secondary" role="alert">...</div>
<div class="alert alert-success" role="alert">...</div>
<div class="alert alert-danger" role="alert">...</div>
<div class="alert alert-warning" role="alert">...</div>
<div class="alert alert-info" role="alert">...</div>
<div class="alert alert-light" role="alert">...</div>
<div class="alert alert-dark" role="alert">...</div>

Fill alert

Add class .alert-fill-* with .alert.

<div class="alert alert-fill-primary" role="alert">
  A simple primary alert—check it out!
</div>

With icon

Add an icon inside the div.

<div class="alert alert-primary" role="alert">
  <i data-feather="alert-circle"></i>
  A simple primary alert—check it out!
</div>

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

<div class="alert alert-primary" role="alert">
  A simple primary alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
</div>

Additional content

Alerts can also contain additional HTML elements like headings, paragraphs and dividers.

<div class="alert alert-success" role="alert">
  <h4 class="alert-heading">Well done!</h4>
  <p>Aww yeah, you successfully read this important alert message. This example text is going to run a bit longer so that you can see how spacing within an alert works with this kind of content.</p>
  <hr>
  <p class="mb-0">Whenever you need to, be sure to use margin utilities to keep things nice and tidy.</p>
</div>

Dismissing

Using the alert JavaScript plugin, it’s possible to dismiss any alert inline.

  • Add a dismiss button and the .alert-dismissible class, which adds extra padding to the right of the alert and positions the .close button.
  • On the dismiss button, add the data-bs-dismiss="alert" attribute, which triggers the JavaScript functionality. Be sure to use the <button> element with it for proper behavior across all devices.
  • To animate alerts when dismissing them, be sure to add the .fade and .show classes.
<div class="alert alert-warning alert-dismissible fade show" role="alert">
  <strong>Holy guacamole!</strong> You should check in on some of those fields below.
  <button type="button" class="btn-close" data-bs-dismiss="alert" aria-label="btn-close"></button>
</div>
