status-messages.html.twig in Drupal 10

Default theme implementation 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 http://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.
