What WCAG 2.4.12 Requires
AAA only: the stricter version of 2.4.11, where the focused element must never be even partially hidden by other content.
Can AccessBell Test This Automatically?
Not fully. Like most WCAG criteria that depend on meaning or context, this one needs a person to judge. AccessBell's report lists it for manual review rather than marking it pass or fail automatically, so it never gets missed.
How to Test It by Hand
Tab through the page and confirm the focused element is fully visible at all times, with no partial overlap.
Common Failures
- A sticky footer partially overlaps the bottom of a focused element, which fails the stricter AAA requirement even if 2.4.11 AA passes.
