Accessible React Interfaces Need More Than ARIA

React does not make an interface accessible or inaccessible by itself. The result depends on the HTML produced, the behavior added, and whether users can understand changes that happen without a full page load.

Begin with native elements. A button already supports keyboard activation and disabled behavior; a clickable div requires those features to be rebuilt. Use labels for inputs, headings in a meaningful order, and landmarks that give the page structure.

Interactive overlays require deliberate focus management. When a dialog opens, move focus into it, keep keyboard navigation within the active dialog, provide an obvious close action, and return focus to the control that opened it. Visual visibility alone is not enough.

Announce important asynchronous results such as failed saves or completed actions when the change may not receive focus. Avoid announcing every minor update, which can make the interface overwhelming.

Test with a keyboard throughout development and include automated accessibility checks in component tests. Then perform targeted manual testing with screen-reader behavior because automated tools cannot judge whether interaction and language make sense. Use ARIA to fill genuine semantic gaps, not to replace native controls. The most dependable accessible component is usually the one that works with the browser rather than fighting it.
