Is CSS modules supported in Vuejs?113

 Is CSS modules supported in Vuejs?

Yes, CSS Modules are indeed supported in Vue.js, and they offer a powerful way to achieve style encapsulation and modularity within your components.

Here's how you can use CSS Modules in your Vue.js project:

1. Setup:

  • File Naming: Save your CSS files with the .module.css extension to indicate they are CSS Modules.

  • Build Configuration: Ensure your build tool (e.g., Webpack) is configured to handle CSS Modules. If you're using Vue CLI, it usually handles this automatically.

2. Importing:

  • Import the CSS Module:


import styles from './my-component.module.css';

3. Applying Styles:

  • Use the imported object as a class binding:

Code snippet

  <div :class="styles.container">

How CSS Modules Work:

  • Local Scope: Each CSS Module creates a unique local scope for its styles, preventing conflicts with styles from other components.

  • Class Name Hashing: Class names are hashed and scoped to the module, ensuring they remain unique throughout the application.



/* my-component.module.css */
.container {
  background-color: blue;

Code snippet

  <div :class="styles.container">

Benefits of CSS Modules:

  • Strong Encapsulation: Prevents styles from leaking between components, ensuring style isolation and maintainability.

  • No Need for Scoped Attribute: Unlike scoped CSS, CSS Modules don't require the scoped attribute, which can have limitations.

  • Dynamic Class Names: Hashed class names help avoid naming conflicts and allow for more dynamic styling patterns.


  • Requires Build Setup: CSS Modules rely on build tools for processing and integration.

  • Learning Curve: Understanding the import and usage syntax might take some initial learning.

Overall, CSS Modules provide a robust and flexible solution for style encapsulation in Vue.js projects, promoting better code organization and maintainability.
