1.4.13 Content on Hover or Focus
호버·포커스 시 나타나는 콘텐츠
Summary
Tooltips and popovers triggered by hover or focus must be hoverable, dismissible (with Escape, for instance), and persistent until dismissed. The driving scenario is a magnifier user moving the pointer onto the tooltip to read it. Losing the content on that move is the classic failure.
Common failures
- A tooltip that vanishes the moment the pointer moves onto it, so magnifier users never finish reading.
- Auto-dismissing after a few seconds, cutting off slower readers.
