ARIA States and Properties
Learn the difference between ARIA states and properties, the kinds of values they take, and the most useful ones: aria-expanded, aria-pressed, aria-checked, aria-selected, aria-current, aria-disabled, aria-invalid, aria-busy, and aria-controls. Includes a state sync lab that shows what goes wrong when state is not updated, a value tester, and a lab for aria-current and aria-busy.
