Enable PostCSS support
In your
rspack.config.js
file, enable the PostCSS loader. See the documentation for more information.rspack.config.jsmodule.exports = { // ... module: { rules: [ { test: /\.css$/, use: ["postcss-loader"], type: "css", }, // ...
Configure your template paths
Add the paths to all of your template files in your
tailwind.config.js
file.tailwind.config.js/** @type {import('tailwindcss').Config} */ export default { content: [ "./src/**/*.{js,ts,jsx,tsx}", ], theme: { extend: {}, }, plugins: [], }
Add the Tailwind directives to your CSS
Add the
@tailwind
directives for each of Tailwind’s layers to your./src/index.css
