To create visually appealing and functional user interfaces in React development, you must properly style your components. Many developers use CSS to style React components. This tutorial will show you How to Import CSS File in React.
What are CSS Modules?
A more contemporary method of styling React that encourages encapsulation and lowers the possibility of style conflicts is the use of CSS Modules. Styles are scoped to particular components with CSS Modules, preventing them from seeping into other areas of the program. This method helps to maintain a tidy and well-organized codebase, which makes it perfect for large applications with several developers.
How to Import CSS File in React
- Install the necessary dependencies and start a new ReactJS project:-
- Use the command below to navigate to your project’s root directory.
Importing an External CSS File:
Put the following code in the file index. CSS.
/* index.CSS */
* {
margin: 0;
}
body {
background-color: aqua;
}
h1 {
border-radius: 20px;
background-color: RGB(251, 141, 196);
text-align: center;
margin-top: 100px;
}
Importing CSS in ReactJs:
import React from ‘react’;
import ReactDOM from ‘react-dom’;
import ‘./index.CSS’;
ReactDOM.render(
<>
<h1> hello Geek!!</h1>
</>
, document.getElementById(“root”)
);
Using Inline CSS in React:
We don’t need to make a separate index.CSS file for this. Using
import React from ‘react’;
import ReactDOM from ‘react-dom’;
ReactDOM.render(
<>
<head>
<style>// importing CSS
{`
body {
margin: 0;
background-color: aqua;
}
`}
</style>
</head>
<body>
<h1 style={{
borderRadius: ’20px’,
backgroundColor: ‘RGB(251, 141, 196)’,
textAlign: ‘center’,
marginTop: ‘100px’
}}> Hello Geek!!</h1>
</body>
</>,
document.getElementById(“root”)
);
Using Internal CSS file in React:
Here is a sample of the code that uses the internal CSS, where all CSS is defined in the tag using the:

ReactDOM.render(
<>
<head>
<style>

* {
margin: 0;
}
body {
background-color: aqua;

`}
</style>
</head>
<body>
<h1>hello Geek!!</h1>
</body>
</>,
document.getElementById(“root”)
);
Benefits of CSS Modules for Large Applications
- Scalability: Encapsulation is encouraged by CSS modules, which facilitates application scaling without causing style conflicts.
- Maintainability: Styles can be scoped to specific components, making updates and maintenance simpler.
- Reduced style conflicts: A cleaner codebase is encouraged by CSS Modules, which make sure that styles don’t seep into other components.
Tips for Managing Styles in React Applications
- To prevent conflicts, give your CSS classes consistent names.
- Keep your CSS files manageable by organizing them. Think about making folders for CSS Modules, component-specific styles, and global styles.
- Reduce the amount of inline styles you use because they are more difficult to maintain and can result in code duplication.
- For added flexibility and maintainability, think about utilizing a CSS-in-JS library like Emotion or styled components.
