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-expandedfor dropdowns) to convey dynamic state information. - Ensure proper labeling: Use
aria-label,aria-labelledby, oraria-describedbyto 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.
