1. Create your project

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

    Terminal
    npx create-next-app@latest my-project --typescript --eslintcd my-project
  2. Install Tailwind CSS

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

    Terminal
    npm install -D tailwindcss postcss autoprefixernpx tailwindcss init -p
  3. 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} */
    module.exports = {
      content: [
        "./app/**/*.{js,ts,jsx,tsx,mdx}",
        "./pages/**/*.{js,ts,jsx,tsx,mdx}",
        "./components/**/*.{js,ts,jsx,tsx,mdx}",
     
        // Or if using `src` directory:
        "./src/**/*.{js,ts,jsx,tsx,mdx}",
      ],
      theme: {
        extend: {},
      },
      plugins: [],
    }
    
  4. Add the Tailwind directives to your CSS

    Add the @tailwind directives for each of Tailwind’s layers to your globals.css file.

    globals.css
    @tailwind base;
    @tailwind components;
    @tailwind utilities;
  5. Start your build process

    Run your build process with npm run dev.

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

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

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