Spotting Keyboard Traps

Find places where focus gets stuck with no exit.

Stuck With No Way Out

A keyboard trap is any spot where focus goes in but cannot get out with the keyboard. For a mouse-free user, it is a dead end. 🪤

Why It Is So Serious

A trapped user may have to reload the whole page just to escape. WCAG calls a no-exit trap a failure, not a minor bug.
