frontend-responsive

Implement mobile-first responsive designs with fluid layouts, breakpoints, relative units, and touch-friendly interfaces that work across all device sizes. Use this skill when writing or modifying React components (.tsx, .jsx files), when implementing CSS or Tailwind responsive utilities (sm:, md:, lg:, xl: breakpoints), when working on layout components, navigation menus, grid systems, when optimizing for mobile devices, tablets, or desktop screens, when implementing media queries, when ensuring touch-friendly UI elements, or when testing cross-device compatibility.
