3.2.1 On Focus
초점 시
Summary
Receiving focus must not, by itself, change the context. Keyboard users tab through elements to survey a page; if merely passing over one navigates away, exploration becomes impossible. Context changes belong to explicit user action.
Common failures
- A select that submits the form or navigates away the moment it receives focus.
