status-messages.html.twig

{#
/**
 * @file
 * 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.
 *
 * Each message block exposes an ARIA live region role so assistive technology
 * user agents announce it appropriately: "alert" for errors and warnings
 * (assertive) and "status" for other message types (polite).
 *
 * 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.
