status-messages.html.twig in Drupal 10

Theme override for status messages.

Displays status, error, and warning messages, grouped by type.

An invisible heading identifies the messages for assistive technology. Sighted users see a colored box. See https://www.w3.org/TR/WCAG-TECHS/H69.html for info.

Add an ARIA label to the contentinfo area so that assistive technology user agents will better describe this landmark.

Available variables:

• message_list: List of messages to be displayed, grouped by type.
• status_headings: List of all status types.
• attributes: HTML attributes for the element, including:
  • class: HTML classes.
