Focus trapping in a React modal requires managing keyboard focus so it cycles only within the modal until closed. This ensures screen reader accessibility by preventing users from navigating to background elements, alongside using correct ARIA attributes to announce the modal's state changes.

Using ARIA attributes for custom React dropdowns involves setting correct roles, states, and properties like aria-expanded and aria-haspopup. You must also implement robust keyboard navigation, allowing users to move through dropdown options using arrow keys and native browser behaviors.

Yes, these accessibility patterns work directly with Next.js applications to ensure compliance with WCAG standards. The approach covers semantic HTML structure, proper ARIA implementation, and focus management specifically within React and Next.js environments.

Semantic HTML is needed as the primary foundation for web accessibility, conveying element purpose natively to assistive technologies. ARIA attributes are required only when semantic HTML is insufficient, such as for custom interactive components where you must explicitly define roles and state changes.

To audit a React component for keyboard navigation and ARIA labeling, verify that all interactive elements are reachable via keyboard and that state changes are correctly announced. Ensure adherence to native browser behaviors and validate that ARIA attributes accurately reflect the component's current state.
