Recommendation to fix
RULE :
Status messages MUST be programmatically determined through role or properties such that they can be presented to the user by assistive technologies without receiving focus.

HOW TO FIX:
Fix this issue by using an ARIA live region so screen readers can automatically announce the status message content.
<div aria-live="assertive">Your form was successfully submitted</div>
<div role="alert">Please correct the errors below to continue</div>
