Introduction to CSS in React: Styling Your Components with Style

Welcome to the realm of styling in React! In this comprehensive guide, we'll explore various approaches to styling React applications, covering traditional CSS, inline styles, CSS Modules, and Styled Components. Understanding these styling techniques will empower you to create visually appealing and responsive user interfaces for your React components.

Traditional CSS

External Stylesheets:

Linking external CSS files is a straightforward way to apply styles to your React components.

Create a CSS file (e.g., styles.css):

/* styles.css */
.container {
  max-width: 800px;
  margin: 0 auto;
}

.button {
  background-color: #3498db;
  color: #ffffff;
  padding: 10px 20px;
  border: none;
  cursor: pointer;
}

Import and use in your React component:

import React from 'react'
import './styles.css'

const MyComponent = () => {
  return (
    <div className='container'>
      <button className='button'>Click me</button>
    </div>
  )
}

export default MyComponent

Inline Styles

Styling with Objects:

Apply styles directly as JavaScript objects using the style attribute.

import React from 'react'

const buttonStyles = {
  backgroundColor: '#3498db',
  color: '#ffffff',
  padding: '10px 20px',
  border: 'none',
  cursor: 'pointer'
}

const MyComponent = () => {
  return (
    <div style={{ maxWidth: '800px', margin: '0 auto' }}>
      <button style={buttonStyles}>Click me</button>
    </div>
  )
}

export default MyComponent

CSS Modules

Local Scoping with Modules:

CSS Modules allow local scoping of styles, preventing class name collisions.

Create a CSS Module (e.g., styles.module.css):

/* styles.module.css */
.container {
  max-width: 800px;
  margin: 0 auto;
}

.button {
  background-color: #3498db;
  color: #ffffff;
  padding: 10px 20px;
  border: none;
  cursor: pointer;
}

Import and use in your React component:

import React from 'react'
import styles from './styles.module.css'

const MyComponent = () => {
  return (
    <div className={styles.container}>
      <button className={styles.button}>Click me</button>
    </div>
  )
}

export default MyComponent

Styled Components

Enhancing CSS with JavaScript:

Styled Components offer a dynamic and component-based approach to styling using JavaScript.

import React from 'react'
import styled from 'styled-components'

const Container = styled.div`
  max-width: 800px;
  margin: 0 auto;
`

const Button = styled.button`
  background-color: #3498db;
  color: #ffffff;
  padding: 10px 20px;
  border: none;
  cursor: pointer;
`

const MyComponent = () => {
  return (
    <Container>
      <Button>Click me</Button>
    </Container>
  )
}

export default MyComponent
