VueJS - CSS Modules

Using CSS Modules with VueJS

CSS Modules allow you to write modular, reusable, and scoped CSS. With VueJS, you can leverage CSS Modules to ensure your styles are scoped to the component and do not leak out. This guide covers how to use CSS Modules in your VueJS applications.

Defining CSS Modules

To define CSS Modules in a Vue component, use the module attribute in the <style> tag:

// MyComponent.vue



                

Using CSS Modules

To use the defined CSS Modules in your template, bind the class names using the $style object:

// MyComponent.vue





                

Combining CSS Modules with Other Styles

You can combine CSS Modules with other scoped or global styles within the same component:

// MyComponent.vue







                

Deep Selector in CSS Modules

To apply styles to deeper elements within a component, use the deep selector in CSS Modules:

// MyComponent.vue




// ChildComponent.vue

                

Best Practices

Follow these best practices when using CSS Modules in VueJS:

• Use Descriptive Class Names: Use clear and descriptive class names to make your styles easier to understand.
• Combine with Scoped Styles: Combine CSS Modules with scoped styles for maximum flexibility and modularity.
• Document Style Usage: Document how and where styles are used to improve maintainability.
• Test Styles Thoroughly: Ensure that your styles are applied correctly by testing them thoroughly in different scenarios.
• Be Mindful of Specificity: Be aware of CSS specificity rules and how they apply to CSS Modules.

Summary

This guide provided an overview of using CSS Modules with VueJS, including defining and using CSS Modules, combining them with other styles, using deep selectors, and best practices. By understanding and utilizing these techniques, you can create modular, maintainable, and scoped styles for your VueJS components.
