  • 4+ years of professional experience building production UIs with semantic HTML and modern CSS
  • Expert-level proficiency in CSS layout (Flexbox, Grid), responsive patterns, and component-based styling
  • Strong accessibility knowledge: semantic structure, ARIA basics, keyboard navigation, focus management, WCAG-aware design
  • Strong understanding of browser behavior: box model, stacking context, positioning, rendering quirks, and cross-browser testing
  • Experience with CSS maintainability: naming conventions (BEM or similar), design tokens, variables, theming
