Modern Tailwind CSS Mastery

Tailwind CSS v4 introduces a revolutionary CSS-first configuration model, moving away from JavaScript-based config files. This skill equips your agent with expert-level knowledge of the v4 engine, focusing on the @theme directive, CSS variables, and high-performance utility patterns.

What it does

• Engine Migration: Seamlessly translates v3 workflows into v4 CSS-first configurations.
• Theme Engineering: Architectures design systems using CSS variables for colors, fonts, and breakpoints.
• Advanced Layouts: Implements modern Flexbox and Grid patterns including auto-fit grids and responsive sidebars.
• Clean Code Architecture: Organizes complex class strings using a logical, multi-step hierarchy (Layout > Box Model > Typography > Modifiers).
• Dark Mode & Variables: Sets up semantic color systems that toggle naturally with the dark: variant.

Why use this skill?

Standard LLMs often hallucinate v3 syntax when asked to write v4 code. This skill ensures your agent uses the latest v4 standards, like the @theme block and the size-* shorthand, while avoiding deprecated patterns and excessive @apply usage. The result is more maintainable, performant, and standard-compliant code.
