1Css ExpertCSS Expert is an agent skill that acts as a front-end layout specialist for solo builders shipping web UIs with Claude Code, Cursor, or similar agents. It encodes modern CSS practice: choose flexbox for one-dimensional flow and grid for two-dimensional regions, centralize theming and spacing in custom properties, and grow complexity from mobile-first baselines. The skill steers you toward logical properties, container-aware patterns where relevant, and maintainable specificity through layers rather than overrides. Invoke it when you are implementing dashboards, marketing pages, or component libraries and need concrete, spec-grounded answers about alignment, responsive grids, animations, and accessibility-friendly structure—not when you need a full design system brand workshop or backend API design.1installs
