Alerts

Provide contextual feedback messages for typical user actions with the handful of available and flexible alert messages.

Examples

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

A simple primary alert—check it out!

A simple secondary alert—check it out!

A simple success alert—check it out!

A simple danger alert—check it out!

A simple warning alert—check it out!

A simple info alert—check it out!

A simple light alert—check it out!

A simple dark alert—check it out!

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

Additional content

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

Well done!

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.

Whenever you need to, be sure to use margin utilities to keep things nice and tidy.

              
  <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>

Icons

Similarly, you can use flexbox utilities and Bootstrap Icons to create alerts with icons. Depending on your icons and content, you may want to add more utilities or custom styles.

An example alert with an icon

              
  <div class="alert alert-warning d-flex align-items-center" role="alert">
    <i class="bi bi-exclamation-triangle me-4"></i>
    <div>
      An example alert with an icon
    </div>
  </div>

Dismissing

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

Be sure you’ve loaded the alert plugin, or the compiled Bootstrap JavaScript.
Add a close button and the .alert-dismissible class, which adds extra padding to the right of the alert and positions the close button.
On the close 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.

Holy guacamole! You should check in on some of those fields below.

              
  <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="Close"></button>
  </div>
