2.1.2 No Keyboard Trap
키보드 함정 없음
Summary
If keyboard focus can move into a component, it must be able to move out again. Getting trapped leaves reloading the page as the only escape, which makes this one of the most immediately damaging failures. Modals and embedded widgets are where it usually happens.
Common failures
- Implementing a modal focus trap without an escape route — no Escape key, no reachable close button.
