Blackout

• Finds all elements on a page that are set as aria-hidden="true" and blacks them out, to visually indicate elements that will not be available to assistive technology (AT) users.
• In addition, also finds aria-hidden elements that are keyboard-focusable (which will be problematic for AT users).
• Visually flags focusable but hidden-to-AT-users with a pulsing red outline.
