Description (*)

Issue : Aria-atomic="true" is missing on error container

Summary: The page contains an error container made with the WAI-ARIA role="alert" attribute, but it does not contain a WAI-ARIA attribute that will make sure all assistive technology can read the error message after more than one invalid submission.

Fix: To make sure that all assistive technologies will read the error message after more than one invalid submission, added the WAI-ARIA attribute aria-atomic="true" to the error container tag.
