AI Agent Skill: Expert UI Design & CSS Styling

AI Agent Skill: Expert UI Design & CSS Styling

This AI agent skill enables users to create and modify user interface components, apply CSS styling, manage frontend architectures, and debug visual issues while adhering to expert-level frontend architecture and design consistency.

What this skill does

• Promotes a CLI-first approach by strictly utilizing native framework CLIs such as `nest g`, `ionic g page`, and `npx shadcn-ui add` for structural generation.
• Enforces the use of utility classes like Tailwind CSS or standard module scoping, minimizing the reliance on custom global CSS overrides.
• Ensures a Mobile-First responsive design strategy, advocating the use of base styles for mobile and exclusive viewport classes (`sm:`, `md:`, `lg:`) for tablet and desktop.
• Makes state management a priority by requiring components to address loading (skeletons/spinners), empty (visual fallbacks), and error states (graceful degradation/toasts).
• Mandates adherence to accessibility standards, including keyboard navigability, semantic HTML, ARIA labels, and proper form associations.
• Facilitates seamless design context acquisition to avoid framework collisions.
• Incorporates visual testing through visual regression or integration testing tools, if available, to verify implementation accuracy.
