Tailwind CSS

Tailwind CSS is a utility-first CSS framework that works exceptionally well with Next.js.

Installing Tailwind​

Install the Tailwind CSS packages and run the init command to generate both the tailwind.config.js and postcss.config.js files:

npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init -p

Configuring Tailwind​

Inside your Tailwind configuration file, add paths to the files that will use Tailwind class names:

import type { Config } from 'tailwindcss'

const config: Config = {
  content: [
    './app/**/*.{js,ts,jsx,tsx,mdx}', // Note the addition of the `app` directory.
    './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: [],
}
export default config
/** @type {import('tailwindcss').Config} */
module.exports = {
  content: [
    './app/**/*.{js,ts,jsx,tsx,mdx}', // Note the addition of the `app` directory.
    './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: [],
}

You do not need to modify postcss.config.js.

Importing Styles​

Add the Tailwind CSS directives that Tailwind will use to inject its generated styles to a Global Stylesheet in your application, for example:

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

Inside the root layout (app/layout.tsx), import the globals.css stylesheet to apply the styles to every route in your application.

import type { Metadata } from 'next'

// These styles apply to every route in the application
import './globals.css'

export const metadata: Metadata = {
  title: 'Create Next App',
  description: 'Generated by create next app',
}

export default function RootLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en">
      <body>{children}</body>
    </html>
  )
}
// These styles apply to every route in the application
import './globals.css'

export const metadata = {
  title: 'Create Next App',
  description: 'Generated by create next app',
}

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

Using Classes​

After installing Tailwind CSS and adding the global styles, you can use Tailwind's utility classes in your application.

export default function Page() {
  return <h1 className="text-3xl font-bold underline">Hello, Next.js!</h1>
}
export default function Page() {
  return <h1 className="text-3xl font-bold underline">Hello, Next.js!</h1>
}

Importing Styles​

Add the Tailwind CSS directives that Tailwind will use to inject its generated styles to a Global Stylesheet in your application, for example:

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

Inside the custom app file (pages/_app.js), import the globals.css stylesheet to apply the styles to every route in your application.

// These styles apply to every route in the application
import '@/styles/globals.css'
import type { AppProps } from 'next/app'

export default function App({ Component, pageProps }: AppProps) {
  return <Component {...pageProps} />
}
// These styles apply to every route in the application
import '@/styles/globals.css'

export default function App({ Component, pageProps }) {
  return <Component {...pageProps} />
}

Using Classes​

After installing Tailwind CSS and adding the global styles, you can use Tailwind's utility classes in your application.

export default function Page() {
  return <h1 className="text-3xl font-bold underline">Hello, Next.js!</h1>
}
export default function Page() {
  return <h1 className="text-3xl font-bold underline">Hello, Next.js!</h1>
}
