To attain this, it’s essential to create a CSS file in your app’s folder, import it into your goal part, and write type guidelines on your app.

To reveal how exterior CSS stylesheets work, you’ll be able to create a CSS file and identify it App.css. You possibly can then export it as follows.

import "./Elements/App.css";

perform App() {

  return (

    <div className="most important">

}

npm set up node-sass

You possibly can then create your recordsdata and provides them a .scss or .sass extension. You possibly can then import your recordsdata within the regular method. For instance;

import "./Elements/App.sass";
