What problem does it solve?
This Skill helps you write, review, and refactor Tailwind CSS v4 code without falling into migration traps, broken utility syntax, or inefficient build setups. It centralizes the most important v4 conventions so teams can produce smaller CSS, cleaner markup, and more consistent design systems.
Core Features & Use Cases
- Build and migration guidance: Choose the right v4 integration path for Vite, PostCSS, or CLI workflows and avoid deprecated configuration patterns.
- Utility and syntax correction: Update renamed classes, variant stacking, opacity syntax, important modifiers, and CSS variable references to v4 standards.
- Design system and theming patterns: Apply CSS-first configuration, semantic tokens, runtime variables, dark mode control, and responsive breakpoints.
- Performance-focused refactoring: Reduce bundle bloat, simplify CSS generation, and favor built-in v4 features like container queries and logical properties.
- Use case: A frontend team migrating a Next.js app to Tailwind v4 can use this Skill to audit existing classes, rewrite configuration, and standardize responsive and dark-mode patterns.
Quick Start
Ask the assistant to inspect your Tailwind CSS v4 files and refactor them to match the skill’s build, utility, theming, and responsive design rules.
