Hi @⛧ RedStar ⛧. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To use Tailwind CSS with Nuxt when using the Rspack builder (builder: 'rspack'), you should avoid using Vite-specific plugins or configurations, as Rspack and Vite are separate build tools and their plugins are not compatible. From the information in your sources, Tailwind CSS is typically integrated in Nuxt via the @nuxtjs/tailwindcss module or by directly including Tailwind in your CSS and configuration. When using Rspack, do not include Vite plugins like @tailwindcss/vite in your vite.plugins array, as this will cause errors—Rspack does not process Vite plugins. Instead, you should: 1. Install Tailwind CSS and its dependencies as usual (e.g., tailwindcss, postcss, autoprefixer). 2. Add your Tailwind CSS file (e.g., '@/styles/main.css') to the css array in your nuxt.config. 3. Do not use the @tailwindcss/vite plugin or any vite: { plugins: [...] } configuration in your nuxt.config when using Rspack. Here’s a minimal example for nuxt.config with Rspack and Tailwind CSS: 
export default defineNuxtConfig({
  builder: 'rspack',
  css: [
    '@/styles/main.css', // Your Tailwind CSS entry
  ],
  // Do NOT include vite: { plugins: [...] } or @tailwindcss/vite
  // Use the @nuxtjs/tailwindcss module if you want auto-configuration:
  modules: [
    '@nuxtjs/tailwindcss'
  ]
})
export default defineNuxtConfig({
  builder: 'rspack',
  css: [
    '@/styles/main.css', // Your Tailwind CSS entry
  ],
  // Do NOT include vite: { plugins: [...] } or @tailwindcss/vite
  // Use the @nuxtjs/tailwindcss module if you want auto-configuration:
  modules: [
    '@nuxtjs/tailwindcss'
  ]
})
If you previously used Vite-specific plugins, remove them from your configuration. The @nuxtjs/tailwindcss module works with all Nuxt builders, including Rspack, and is the recommended way to add Tailwind CSS in a builder-agnostic manner. If you still encounter errors, ensure that all Vite-related configuration is removed and that you are not importing Vite plugins anywhere in your project. The knowledge sources do not provide a detailed step-by-step for Rspack + Tailwind, but they do indicate that Rspack is a separate builder and should not be mixed with Vite plugins or configuration. If you need more advanced configuration, refer to the official Nuxt Tailwind module documentation and ensure compatibility with Rspack. I'm sorry, but the knowledge sources do not provide more detailed troubleshooting steps for Tailwind CSS with Rspack specifically. If you encounter a specific error, please provide the error message for more targeted help. References:
