npx tailwindcss init -p

This will generate tailwind.config.js and postcss.config.js.

Step 2: Configure Template Paths

In tailwind.config.js, define your content paths:

module.exports = {
  content: [
    './app/**/*.{js,ts,jsx,tsx,mdx}',
    './pages/**/*.{js,ts,jsx,tsx,mdx}',
    './components/**/*.{js,ts,jsx,tsx,mdx}',
  ],
  theme: {
    extend: {},
  },
  plugins: [],
}

Step 3: Add Tailwind Directives to CSS

In app/globals.css, add the following:

@tailwind base;
@tailwind components;
@tailwind utilities;

Step 4: Import CSS in Root Layout

In app/layout.tsx, import your global styles:

import './globals.css'

export default function RootLayout({ children }) {
  return (
    <html lang="en">
      <body>{children}</body>
    </html>
  )
}

Conclusion

With Tailwind CSS v3 installed in your Next.js app, you can build modern, responsive UIs quickly. These basic setup steps can be extended with plugins, custom themes, and utility classes to match your design system.
