Styling React Using Sass

What is Sass ?

Sass is a CSS pre-processor.

Sass files are executed on the server and sends CSS to the browser.

You can learn more about Sass in our Sass Tutorial.

Can I use Sass?

If you use the create-react-app in your project, you can easily install and use Sass in your React projects.

Install Sass by running this command in your terminal:

npm i sass

Now you are ready to include Sass files in your project!

Create a Sass file

Create a Sass file the same way as you create CSS files, but Sass files have the file extension .scss

In Sass files you can use variables and other Sass functions:

Example

my-sass.scss:

Create a variable to define the color of the text:

$myColor: red;

h1 {
  color: $myColor;
}

Import the Sass file the same way as you imported a CSS file:

Example

index.js:

import React from 'react';
import ReactDOM from 'react-dom/client';
import './my-sass.scss';

const Header = () => {
  return (
    <>
      <h1>Hello Style!</h1>
      <p>Add a little style!.</p>
    </>
  );
}

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(<Header />);
