Capability checkAct without hover
Hover-only menus, tooltips, and disclosures fail “Act without hover.” Agents do not move a pointer — they keyboard-focus and click — so content that only exists on :hover is invisible to them.
How to fix it
Reveal the same content on focus as well as hover, or expose it as visible text and focusable controls.
Reveal on focus too
/* before: hover only */
.menu { display: none; }
div:hover .menu { display: block; }
/* after: keyboard reachable too */
.menu { display: none; }
div:hover .menu,
button:focus-visible + .menu { display: block; }See if your page fails this rule.
