Using Global Styles with CSS

Global CSS in Next.js is defined in the pages/_app.js file. To add a global stylesheet:

1. Create a styles directory at the root of your Next.js project.
2. Add a global CSS file, e.g., global.css, in the styles directory.
3. Import the stylesheet in pages/_app.js:

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

function MyApp({ Component, pageProps }) {
  return <Component {...pageProps} />
}

export default MyApp;

Component-Level Styling with CSS Modules

Next.js supports CSS Modules by default. To style components individually:

1. Create a CSS file with the .module.css extension in the same directory as your component, e.g., Button.module.css.

/* Button.module.css */
.button {
  background-color: #0055ff;
  color: white;
  padding: 10px 20px;
  border-radius: 5px;
}

2. Import the module in your component:

// Button.js
import styles from './Button.module.css';

function Button() {
  return <button className={styles.button}>Click Me</button>;
}

export default Button;

Utilizing Styled JSX

Styled JSX is another powerful styling solution that comes with Next.js, offering scoped CSS directly within components.

// ComponentWithStyledJsx.js
function ComponentWithStyledJsx() {
  return (
    <div>
      <p>Hello, Styled JSX!</p>
      <style jsx>{`
        p {
          color: teal;
          font-size: 18px;
        }
      `}</style>
    </div>
  );
}

export default ComponentWithStyledJsx;

Leveraging SASS/SCSS

Next.js supports SASS/SCSS, offering a richer styling experience.

1. Install SASS:

npm install sass

2. Create a SCSS file, e.g., styles.scss, and import it in pages/_app.js.

/* styles.scss */
$primary-color: #3490dc;

body {
  background-color: $primary-color;
}

Advanced Styling with Tailwind CSS

Tailwind CSS has become increasingly popular for utility-first CSS frameworks. It's easy to integrate with Next.js.

1. Install Tailwind CSS:

npm install tailwindcss postcss autoprefixer
npx tailwindcss init

2. Configure Tailwind to remove unused styles in production:

• Add the paths to all of your template files in your tailwind.config.js file.
• Import Tailwind’s base, components, and utilities styles in your global CSS file.

/* globals.css */
@tailwind base;
@tailwind components;
@tailwind utilities;

By following the above approaches, you can effectively manage CSS styling in your Next.js projects in 2025, enhancing the user interface and user experience.
