Users who navigate by keyboard (people with motor disabilities, power users, people in assistive technology contexts) rely entirely on focus indicators to know where they are on the page. Removing outlines without replacement makes an entire site unusable for keyboard users. WCAG 2.4.7 requires a visible focus indicator, and WCAG 2.4.13 defines a stronger size-and-contrast target for custom indicators.
overflow: hiddenFind all instances of outline: none, outline: 0, or :focus { outline: none } in this CSS. Check if they provide an alternative visible focus indicator. If the replacement uses pseudo-elements, also verify the ring cannot be clipped or misplaced by overflow or missing positioning context.
Replace outline: none on :focus with :focus-visible styles that provide a clearly visible custom focus ring with appropriate contrast.
Explain the difference between :focus and :focus-visible, why focus styles matter for accessibility, and how to design an accessible focus ring.
Review stylesheets, component styles, and responsive states related to Provide visible custom focus indicators. Flag exact selectors, declarations, or breakpoints that violate the rule in the rendered UI.
