To set up Tailwind v4 theming with shadcn/ui, you need to map CSS variables via @theme inline, apply base layer styles, and integrate a theme provider. This ensures semantic color mapping and automatic dark mode support across your components.

Migrating to Tailwind v4 semantic colors involves defining root CSS variables and mapping them through @theme inline. This approach transitions your project to a theme-driven color system with proper dark mode handling for shadcn/ui components.

Yes, shadcn/ui dark mode works automatically with Tailwind v4 when you map semantic color variables via @theme inline and integrate a theme provider. This configuration ensures dark mode is operable without manual toggling logic.

A modern React + Vite workflow is required to properly configure Tailwind v4 theme variables with shadcn/ui. Vite ensures dependencies are installed correctly and CSS variables are mapped efficiently for dark mode and semantic color application.

Your shadcn/ui theming may not work because CSS variables are not mapped via @theme inline. Tailwind v4 requires this specific four-step pattern: root definitions, inline mapping, base layer application, and dark mode support to function correctly.

Yes, you can use it for new project initialization to establish a robust theming foundation. It automates setting up semantic color variables, dark mode, and theme provider integration for shadcn/ui components from the start.
