Describe your issue

I have some css files ans HTML files. The HTML contains some tailwindcss classes like p-2 etc. If i run vite build --watch the first build is correct. And the p-2 css Definition is in the Output css. But if i change the classes in the HTML it recompiles but dont get the new classes. If i use @apply in my source css file the Compiler works every time. So must be a bug in the HTML stuff.

@KartoffelToby Heya! Do you have a repro that you can share? We've been looking into the Vite plugin just last week and as a result of that also added a new integration test that does cover changing a .html file in watch mode if you need a starting point.

1. Check Vite Configuration:
Ensure that your Vite configuration is set up correctly to watch for changes in HTML files. Your vite.config.js should include the HTML files in the build.rollupOptions.input configuration.

import { defineConfig } from "vite"
import path from "path"

export default defineConfig({
  build: {
    rollupOptions: {
      input: {
        main: path.resolve(__dirname, "index.html"),
        // Add other HTML entry points here
      }
    }
  }
})

2. Tailwind CSS Configuration:
Make sure your tailwind.config.js is correctly configured to purge unused styles from the correct files. For example:

module.exports = {
  content: [
    "/index.html",
    "./src/**/*.{js,ts,jsx,tsx,html}",
  ],
  theme: {
    extend: {},
  },
  plugins: [],
}

3. Update Dependencies:
Ensure all dependencies are up-to-date, including Vite and Tailwind CSS. Run:
npm update
