Accessibility Checking for Large Sites

Rocket Validator integrates axe-core version 4.4, into an automated web site scanner.

Ensures <frame> and <iframe> elements with focusable content do not have tabindex=-1

%lt;frame%gt; and %lt;iframe%gt; elements with focusable content must not have tabindex="-1".

When a frame has a negative tabindex, the browser is prevented from redirecting the focus to the content inside that frame. This causes all its content from getting skipped in keyboard navigation, and if the frame is scrollable also prevents the focus from reaching any element from which the frame can be scrolled with the keyboard.
