What WCAG 2.4.13 Requires
AAA only: the visible focus indicator must meet minimum size, contrast and area requirements, going beyond simply being visible at all.
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
Measure a focus indicator's thickness, contrast and area against the specific AAA thresholds in the success criterion.
Common Failures
- A thin 1px focus outline is technically visible but does not meet the minimum area and contrast the AAA level requires.
