Stop wrestling with CSS. Start shipping features.

Component scaffolding

Describe a UI component in plain language and get a fully typed React/Vue/Svelte component with props, states, event handlers, accessibility attributes, and Storybook stories.

CSS and layout debugging

Paste a screenshot or describe the visual bug. Claude Code reads your styles, identifies the issue, and applies the fix — whether it is a flexbox alignment, z-index stacking, or responsive breakpoint problem.

Design system implementation

Claude Code converts Figma token exports into CSS custom properties, generates component variants that match your design system, and ensures consistent spacing, typography, and color usage.

Test coverage for UI components

Generate comprehensive tests using Testing Library and Vitest/Jest. Claude Code writes tests that check rendering, user interactions, accessibility, and edge cases like loading and error states.

Performance optimization

Claude Code analyzes your bundle, identifies unnecessary re-renders, suggests code splitting points, and implements lazy loading — then verifies the improvements with Lighthouse audits.

Frontend development involves an enormous surface area: HTML semantics, CSS layout, JavaScript logic, TypeScript types, accessibility standards, responsive design, browser compatibility, performance budgets, and testing. Claude Code handles all of these simultaneously. When you ask it to build a component, it does not just write JSX — it considers ARIA attributes, keyboard navigation, screen reader announcements, focus management, and responsive behavior. This depth of understanding saves hours of manual work on every feature.

Claude Code adapts to your framework of choice. In a Next.js project, it uses App Router conventions, Server Components where appropriate, and proper metadata exports. In a Vue project, it follows Composition API patterns with script setup. It detects your project's patterns from existing code and matches them, so new components feel like they belong in your codebase rather than being pasted from a tutorial.
