1. Install the sass package:

npm i sass -D

2. Add new files with the .scss extension to the styles folder (or rename existing .css files to .scss), like this:

3. Last but not least, update the places where you previously imported css files to scss:

// pages/_app.js
import "../styles/globals.scss";

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


In this example, we’ll use the nesting feature provided by SASS with BEM naming for classes.

Note: BEM stands for Block, Element, and Modifier. It’s a naming convention whose goal is to facilitate modularity and make styles and classes a lot easier to maintain.


Here’s the code for pages/index.js:

// pages/index.js
import styles from  "../styles/Home.module.scss";

export default function Home() {

    <div className={styles.home}>
      <div className={styles.home__header}>
      <div className={styles.home__main}>

.home {
  padding: 30px;

  &__header {
    h1 {
      color: blue;

  &__main {
    padding: 30px;
    background: rgb(240, 240, 200);
    p {
      color: red;
