Building Fast, Accessible UIs with React and Tailwind
Performance budgets, keyboard navigation and component patterns for production React apps paired with Tailwind CSS v4.

Fast UI is accessible UI. When React components re-render unnecessarily or Tailwind bundles bloat, everyone suffers — especially users on mobile networks and assistive technologies.
Component boundaries
Split containers (data fetching) from presentational components. Memoize expensive lists. Prefer composition over prop drilling; use context sparingly for theme and auth only.
Accessibility checklist
Every interactive element needs focus states, ARIA labels where semantics are insufficient, and colour contrast above WCAG AA. Test with keyboard-only navigation before every release.
Tailwind v4 with Laravel Vite
Use @source directives to scan Blade and JSX. Purge unused utilities in production builds. Co-locate component classes with @apply only for repeated design tokens — avoid @apply soup.
