React CSS Styling

In this tutorial, we'll explore different approaches to styling React components using CSS.

We'll cover various techniques and libraries that can help you style your components in a modular, maintainable, and efficient manner.

What is Inline Styling?

React allows you to apply inline styles directly to your components using the style prop. With inline styling, you can define CSS properties as JavaScript objects. This approach is useful for simple styles or for applying dynamic styles based on component state or props. However, it can become cumbersome for complex styles.

What are CSS Modules?

CSS Modules is a technique that allows you to write CSS stylesheets in a modular manner and import them directly into your React components. It scopes the styles to the specific component, preventing style clashes with other components. CSS Modules are a great choice for medium-sized applications where you want to keep your styles localized.

What is CSS in JS?

CSS-in-JS is a modern approach to styling in React, where you write your styles directly in JavaScript code. It offers a powerful way to create dynamic and reusable styles using JavaScript logic.

There are various CSS-in-JS libraries available, such as styled-components, emotion, and JSS, each with its own syntax and features. CSS-in-JS is particularly beneficial for large-scale applications and provides a convenient way to handle complex styling requirements.

What are styled components in React CSS?

Styled Components is a popular CSS-in-JS library that allows you to write CSS styles using JavaScript syntax. It offers a convenient way to create reusable and composable styled components.

With Styled Components, you can define styles directly inside your component's JavaScript code, providing better encapsulation and modularity.

Each approach has its own strengths and is suitable for different scenarios. Choose the approach that best fits your project's requirements and preferences. Experiment with different styling techniques to create visually appealing and well-structured React applications.

Next, we are going to learn about React SCSS Styling.


Overriding default styles of a React component library can be done using CSS specificity. Use more specific CSS selectors or use !important for critical changes. However, it's recommended to avoid using !important as it can lead to maintainability issues. Prefer using CSS modules or CSS-in-JS libraries to encapsulate styles and prevent global conflicts.

Yes, you can use CSS animations and transitions in React components. Define your animations and transitions using CSS classes or inline styles, and then apply them to your React components. Use CSS classes to trigger animations based on state changes or user interactions. For more complex animations, consider using CSS animation libraries like react-transition-group.

To use third-party CSS libraries in ReactJS, install them using npm or yarn and then import them into your components. You can use the library's predefined classes or styles within your components as needed. If the library provides JavaScript functionality, follow the library's documentation to integrate it into your React application.
