Answer

ARIA (Accessible Rich Internet Applications) attributes provide additional context for assistive technologies:

  • Use ARIA roles: Define the purpose of UI elements (e.g., role='button') where native semantics are insufficient.
  • Implement ARIA states: Indicate changes in the UI (e.g., aria-expanded for dropdowns) to convey dynamic state information.
  • Ensure proper labeling: Use aria-label, aria-labelledby, or aria-describedby to enhance user understanding of elements.
  • Avoid misuse: Use ARIA only when native HTML elements do not suffice, as it can sometimes create confusion if overused.
