Why Keyboard Navigation Matters
Keyboard navigation is essential for users who cannot use a mouse, including people with motor disabilities, power users, and screen reader users.
Core Keyboard Navigation Concepts
Tab Order
The tab key moves focus through interactive elements in DOM order. Ensure your visual layout matches the DOM order for intuitive navigation.
Focus Indicators
Users must always know which element has focus. Never remove focus outlines without providing an alternative.
Skip Links
Allow users to bypass repetitive navigation and jump directly to main content.
Building Accessible Components
Focus Management for Modals
When opening a modal:
Keyboard-Accessible Dropdowns
Implement arrow key navigation for dropdown menus.

Use proper ARIA roles and keyboard patterns for custom UI components.
