The art of incorporating CSS style files in Next.js

Just starting out with Next.js and I could use some help.

I'm having trouble getting all of the styles and images to work properly even though I've declared the css files in _app.tsx. Some styles are not being applied and images from 'public/images' are not being imported. Can you help me figure out what's causing this issue? Do I need to reorganize my folder structure? The version of Next.js I'm using is "13.1.1".

Thank you in advance for any assistance!

Here is the folder structure for the project I'm working on:

public
- fonts
- images
src
- pages
- styles
  - global.css
  - layout.css

This is how my _app.tsx file is set up:

import '@/styles/layout.css';
import '@/styles/common.css';

export default function App({ Component, pageProps }: AppProps) {
 ...
}

Answer №1

Make sure to appropriately name your CSS file as layout.module.css. It is recommended to use the .module.css extension for your CSS files. For more information, you can refer to the nextjs documentation.

Next.js can be frustrating at times because it doesn't seem to respect the idea that "static content is static content." However, when it comes to CSS, you can still use traditional CSS files in a separate directory without having to deal with the complexities of "CSS modules" within JavaScript:

If you don't already have a globals.css file in your app directory, create one.
Include import "globals.css" in your global page.tsx file if it's not there already.

(These steps are usually taken care of if you used next create to set up your project directory)

If you don't already have a separate folder for your .css file(s), create one.
In globals.css, add a standard CSS @import url(...) for your file(s).
That's it.

Now it's just a matter of regular web development work: design the CSS the way you want, especially now that SASS is no longer necessary thanks to CSS variables being supported since 2018, and nested rules being added in late 2023.

(For organization purposes, consider creating a master file like style.css so you only need one import in globals.css and can avoid touching that file again. If you have multiple CSS files, simply include @import statements in your master file, following the familiar structure of regular web development)

Just delving into the world of Nextjs and discovered that traditional CSS files won't work; instead, you have to utilize CSS modules.

Remember to change the file extension of each CSS file (except for global styles) to .module.css rather than .css. Next, import the file into the component you wish to style:

import styles from 'style/file.module.css'

To style an element, define a class in the CSS file: .paragraph{ color:green }

Then, apply it in the component:

        <p className={styles.paragraph}>I am styled with CSS modules</p>

Reference!
