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


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). For inline dismissal, use the alerts JavaScript plugin.


Link color

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


Additional content

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



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



Need more than one icon for your alerts? Consider using more icons and making a local SVG sprite like so to easily reference the same icons repeatedly.



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.
