Alert

Demonstration

An informational standard alert message or callout.

Code

Alerts contain contextually relevant messages for the user. They may be used to indicate a successful or unsuccessful interaction, provide feedback for form inputs, or display time-sensitive information about content within a view. Further guidance on Alerts can be found on the U.S. Web Design System (USWDS) site.


The standard Alert is suited for standard information such as inline call-outs or supplemental information. It doesn’t interrupt the user’s workflow, so the role is set to region and paired with an aria-describedby attribute targeting the body of the alert.
