Demonstrate the integration of Tailwind CSS with Next.js 14 to rapidly customize and build complex layouts with utility-first CSS classes.
// pages/_app.js
import '../styles/globals.css';

function MyApp({ Component, pageProps }) {
  return <Component {...pageProps} />;

export default MyApp;
This is the Next.js custom App component that initializes pages. It imports the global stylesheet where Tailwind CSS directives will be placed.
// styles/globals.css
@tailwind base;
@tailwind components;
@tailwind utilities;
This is the global stylesheet file where Tailwind CSS directives are imported. It allows Tailwind to inject its base, component, and utility styles.
// tailwind.config.js
module.exports = {
  content: ['./pages/**/*.{js,ts,jsx,tsx}', './components/**/*.{js,ts,jsx,tsx}'],
  theme: {
    extend: {},
  plugins: [],
This is the Tailwind CSS configuration file. It specifies where Tailwind should look for class names (in the pages and components directories) and allows customization of the theme.
// pages/index.js
export default function Home() {
  return (
    <div className='flex justify-center items-center h-screen'>
      <h1 className='text-5xl font-bold'>Welcome to Next.js with Tailwind CSS!</h1>
This is a sample index.js file showcasing a basic layout using Tailwind CSS utility classes for styling. It centers a heading on the screen both vertically and horizontally.
// postcss.config.js
module.exports = {
  plugins: {
    tailwindcss: {},
    autoprefixer: {},
This is the PostCSS configuration file necessary for processing Tailwind CSS. It includes the tailwindcss plugin and the autoprefixer for adding vendor prefixes to CSS rules.
