import css in react

Incorporating Cascading Style Sheets (CSS) in React can be crucial to the functionality and overall aesthetic of an application, letting you structure, design, and lay out your web page as desired. This article aims to guide you on how to import CSS into your React application using a very basic example.

Code Snippet “Importing CSS in React”

You can import CSS file into your React component as follows:

import React from 'react';
import './App.css';

function App() {
  return (
    <div className="App">
      <header className="App-header">
        <h1>Welcome to my App</h1>
      </div>
    </div>
  );
}

export default App;

Meanwhile, your CSS should be appropriately linked in your App.css file:

.App {
  text-align: center;
}

.App-header {
  background-color: #282c34;
  padding: 20px;
  color: white;
}

Code Explanation for “Importing CSS in React”

In this tutorial, we thoroughly check the process of CSS importation in React through easy-to-understand steps.

First, analyze the React component code. Here, you see import './App.css' at the top, indicating that we are importing a CSS file from the same directory where our React component file is located, in this case, the App file.

After importing, we can use the CSS styles defined in App.css in our React App component. So, in this application, we’re applying some styling to a <div>, which gets the className of “App”, and a <header>, which receives the className of “App-header”.

Turn now to the App.css file. The .App CSS class sets the text alignment of our <div> inside the App component to the center. Nestled inside this <div> is our <header> with the App-header class, which sets the background color, padding, and text color.

Remember, in React, you use className instead of the class attribute for adding CSS classes to your JSX elements. This method is a general principle when working with CSS in React applications, and it helps streamline your code and increases legibility and organization of your design components.

By importing CSS into your React application, it allows you to isolate and manage styles on a component-by-component basis, making your app more scalable and easier to maintain.
