Styling in Next.js

1. Introduction

Next.js is a powerful framework for building React applications. It provides multiple options for styling components, allowing developers to choose the approach that best fits their needs.

2. CSS Modules

CSS Modules are a popular way to style components in Next.js, offering scoped styles to avoid conflicts.

/* styles.module.css */
.container {
    background-color: #f0f0f0;
    padding: 10px;
}
            

/* Component.js */
import styles from './styles.module.css';

const MyComponent = () => {
    return 
Hello, CSS Modules!
;
};

export default MyComponent;
            

3. Styled JSX

Styled JSX is the default scoped styling solution for Next.js, allowing you to write styles directly within your components.

const MyComponent = () => {
    return (
        

            
Hello, Styled JSX!
            
        
    );
};

export default MyComponent;
            

4. Global Styles

Global styles can be defined in Next.js by importing a CSS file in the custom _app.js file.

/* styles/global.css */
body {
    margin: 0;
    font-family: Arial, sans-serif;
}

/* _app.js */
import '../styles/global.css';

function MyApp({ Component, pageProps }) {
    return ;
}

export default MyApp;
            

5. Best Practices

• Use CSS Modules for component-specific styles to avoid naming conflicts.
• Utilize Styled JSX for dynamic styling within components.
• Keep global styles to a minimum to maintain modularity.
• Use meaningful class names to enhance readability.
