1. Create your project

    Start by creating a new Remix project if you don’t have one set up already. The most common approach is to use Create Remix.

    Terminal
    npx create-remix@latest my-projectcd my-project
  2. Install Tailwind CSS

    Install tailwindcss, its peer dependencies, and concurrently via npm, and then run the init command to generate both tailwind.config.js and postcss.config.js.

    Terminal
    npm install -D tailwindcss postcss autoprefixer concurrentlynpx tailwindcss init
  3. Configure your template paths

    Add the paths to all of your template files in your tailwind.config.js file.

    tailwind.config.js
    module.exports = {
      content: [
        "./app/**/*.{js,ts,jsx,tsx}",
      ],
      theme: {
        extend: {},
      },
      plugins: [],
    }
    
  4. Update your package.json scripts

    Update the scripts in your package.json file to build both your development and production CSS.

    package.json
    {
      "scripts": {
        "build": "npm run build:css && remix build",
        "build:css": "tailwindcss -m -i ./styles/app.css -o app/styles/app.css",
        "dev": "concurrently \"npm run dev:css\" \"remix dev\"",
        "dev:css": "tailwindcss -w -i ./styles/app.css -o app/styles/app.css",
      }
    }
    
  5. Add the Tailwind directives to your CSS

    Create a ./styles/app.css file and add the @tailwind directives for each of Tailwind’s layers.

    app.css
    @tailwind base;
    @tailwind components;
    @tailwind utilities;
  6. Import the CSS file

    Import the compiled ./app/styles/app.css file in your ./app/root.jsx file.

    root.jsx
    import styles from "./styles/app.css"
    
    export function links() {
      return [{ rel: "stylesheet", href: styles }]
    }
  7. Start your build process

    Run your build process with npm run dev.

    Terminal
    npm run dev
  8. Start using Tailwind in your project

    Start using Tailwind’s utility classes to style your content.

    index.jsx
    export default function Index() {
      return (
        <h1 className="text-3xl font-bold underline">
          Hello world!
        </h1>
      )
    }
