We'll be using Tailwind CSS to style our storefront. Let's begin by installing the required development dependencies (using the flag -D below), and configuring PostCSS.

Inside the terminal, run the following:

npm install -D tailwindcss autoprefixer postcss

We'll now need to generate the files tailwind.config.js and postcss.config.js where we can customize the config for the newly installed dependencies.

Inside the terminal, run the following:

npx tailwindcss init -p

You will now see both files in the root of the project.

Open tailwind.config.js and configure the template paths using the content array:

module.exports = {
  content: [
  theme: {
    extend: {},
  plugins: [],

Finally, inside pages/_app.tsx add the following import at the top:

import "tailwindcss/tailwind.css";

Your pages/_app.tsx should look something like this:

import "tailwindcss/tailwind.css";
import type { AppProps } from "next/app";

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

export default MyApp;

Now let's add a Tailwind class to our homepage h1. Inside pages/index.tsx update the h1 to include the following className:

import type { NextPage } from "next";

const Home: NextPage = () => {
  return <h1 className="text-purple-500 text-xl">Hello world</h1>;

export default Home;

Finally, let's start the Next.js app and see our styled h1 at http://localhost:3000:

npm run dev
