3.2 Predictable · Understandable
WCAG 3.2.1 On Focus
Level A
Focusing a component must not trigger a change of context (open a new window, submit a form, move focus elsewhere).
Common failures
- Tabbing to a `<select>` auto-submits the form.
- Focus on a link auto-navigates.
How to fix
- Bind context changes to explicit user activation, not focus events.
