Why should I use OKLCH colors in v4?

Tailwind v4 encourages OKLCH because it provides perceptually uniform lightness and better support for high-gamut displays compared to Hex or HSL.

Is the theme() function still used in v4?

While it still exists, v4 encourages using standard CSS var() syntax instead of the theme() function for better native browser compatibility.

What is the biggest change in Tailwind CSS v4?

The most significant change is the CSS-first configuration, which replaces the JavaScript-based tailwind.config.js with @theme blocks directly inside your CSS files.

How does this skill help with Tailwind v3 migration?

It provides specific instructions for updating dependencies, converting legacy configuration files to CSS variables, and replacing outdated @tailwind directives with modern @import syntax.

Does this skill support shadcn/ui?

Yes, it includes specific patterns for updating shadcn/ui global styles to align with Tailwind v4's layer system and CSS variable requirements.
