CSS-in-JS
CSS-in-JS is an approach to styling web applications dynamically. Here CSS styles are composed using JavaScript instead of traditional CSS files. This approach gained popularity within the React community and has since been adopted by other frontend frameworks and libraries
Features:
- Scoped Styles: With CSS-in-JS libraries like Styled Components or Emotion, styles are scoped to the component level by default, reducing the chance of style conflicts.
- Dynamic Styling: CSS-in-JS allows for dynamic styling based on props or state, enabling more flexibility and reusability in component design.
- Enhanced Readability: Styles are often co-located with the component code, which can improve readability and maintainability, especially for smaller components.
- Performance: CSS-in-JS libraries often generate styles dynamically, which can impact initial loading times compared to precompiled CSS. However, this overhead is usually negligible in most applications.
- Tooling Integration: CSS-in-JS libraries often offer tooling integration for features like theming, server-side rendering, and code splitting, which can streamline the development process.
Example: Below is an example of styling React Components in CSS-in-JS.
import React from 'react';
function Card() {
const cardStyle = {
width: '300px',
padding: '20px', borderRadius: '10px',
border: '1px solid green'
};
const btnStyle = {
padding: '10px',
borderRadius: '5px',
border: '1px solid green'
};
return (
<div style={cardStyle}>
<img src="https://media.w3wiki.org/gfg-gg-logo.svg"
alt="gfg-logo" />

);
}
export default Card;

Styling React Components: CSS vs CSS-in-JS
When it comes to styling React components, developers often face the dilemma of choosing between traditional CSS and CSS-in-JS solutions. Both approaches offer unique advantages and drawbacks, influencing how developers design and maintain their application’s user interface.
In this article, we delve into the differences between CSS and CSS-in-JS, exploring their syntax, dynamic styling capabilities, and integration with React. By understanding the variation of each approach, developers can make informed decisions on how to best style their React components for optimal performance, maintainability, and scalability.
