Alerts

Bootstrap alerts are feedback messages which are displayed after specific actions preceded by the user. Length of the text is not limited.

Simple Alert

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

Icons

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

                            </div>

Dismissing

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

<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">
    <span aria-hidden="true">&times;</span>
  </button>
</div>
