Alerts display a status update, reflecting a user or system action.


Alerts are often time-sensitive. Alerts can update themselves or may require a user action. Alerts may be used to display text, icons, or actions.

  1. Icon
  2. Close button
  3. Container
  4. Label

Alerts have four core types — basic, with button, with title, and with title and bottom button.

Note: The bottom button variation is currently design-only and we are working towards releasing this work in a future version of UI Toolkit.
