Accessible Widgets, Dialogs, and ARIA
Some UI pieces are more complex than buttons and forms. They still need keyboard support, focus control, and good screen-reader meaning.
A school auditorium needs more than just a door. It also needs signs, guided seating, and clear rules so everyone can enter, move, and exit safely.
Topic practice prompts
Use the right dialog semantics, move focus into the dialog, keep keyboard users inside it while open, and return focus when it closes.
- How do you trap focus?
- What should happen when the dialog closes?
Use ARIA when native HTML is not enough for a complex widget. Avoid it when native elements already provide the correct semantics and behavior.
- Why is a div button usually worse than a real button?
- What does aria-live solve?
Last-day revision lines
- Focus in, focus out, focus return.
- Match ARIA to interaction.
- Keep state names clear.
- Test with keyboard first.
