Modal Dialog Accessibility Issues - Focus Trap Not Working

Modal dialogs aren't accessible. Users can tab to elements behind the modal, keyboard focus isn't trapped, or screen readers don't announce the modal.

Accessibility testing tools flag issues with focus management and ARIA attributes.

Error Messages You Might See

Focus escapes modal to background Screen reader doesn't announce modal No way to close without mouse Keyboard navigation broken in modal

Common Causes

  1. No focus trap - focus can escape to background content
  2. Missing dialog role or aria-modal attribute
  3. ESC key doesn't close modal
  4. No aria-labelledby or aria-describedby
  5. Background content not marked inert

How to Fix It

Use accessible modal library: react-modal, headless-ui, or radix-ui Dialog

Or implement: focus-trap package for managing focus

Add attributes: role='dialog' aria-modal='true' aria-labelledby='title'

Close on ESC: window.addEventListener('keydown', e => e.key === 'Escape' && closeModal())

Mark background inert:

{content}
