tailwind-v4-shadcn

To set up Tailwind v4 with shadcn/ui, apply a CSS-first configuration using a four-step pattern: define root CSS variables, map them with @theme inline, apply base styles, and enable automatic dark mode for reliable theme-aware UI.

Tailwind v3 to v4 migration breaks dark mode when relying on fragile JavaScript configs instead of a CSS-variable architecture. Enforcing CSS-first configuration with @theme inline mapping and ThemeProvider integration prevents these common migration pitfalls.

The best way to configure dark mode for shadcn/ui in React is through a CSS-variable theming architecture. This approach ensures consistent theming, accessible color tokens, and smooth dark-mode behavior by using automatic dark-mode integration.

You do not need a JavaScript config file for Tailwind v4 and shadcn/ui theming. The setup enforces a CSS-first configuration approach, replacing fragile config files with a robust CSS-variable architecture for reliable theming.

You can use Tailwind v4 CSS variables for consistent theming across teams. This skill provides production-ready templates and reference docs that standardize the setup, reducing migration risk and accelerating project onboarding.

There are no inherent limitations to using CSS variables for shadcn-ui themes in Tailwind v4. This approach replaces fragile configs with a robust architecture, reducing migration risk and ensuring smooth dark-mode behavior across React projects.
