Building accessible React components requires semantic markup, appropriate ARIA roles, and strict keyboard focus management to satisfy WCAG 2.1 AA standards. This ensures interfaces remain fully usable via keyboard navigation across all responsive breakpoints.

The best way to separate data fetching from presentation is using container components to manage data logic and presentational components to render the UI. This composition pattern ensures focused single-responsibility components and maintainable frontend architecture.

Implement responsive layouts by applying mobile-first breakpoints and referencing semantic design tokens for spacing scales and typography hierarchy. This ensures visual consistency and strict adherence to the project's established design system.

Add skeleton loading, error, and empty states to a React list component by managing distinct UI states within your presentational component. This provides visual feedback during data fetching and handles edge cases for a polished user experience.

Yes, you can apply this component architecture and state management approach without external dependencies. It relies on native React composition-over-configuration patterns, colocation, and single-responsibility principles to build production-quality interfaces.
