CSS Modules

CSS modules offer a way to break styles into smaller, reusable units. This helps keep project code clear and easy to maintain.

Why use modules?

The essence of the modular approach is that each component has its own isolated style. This prevents style conflicts and ensures that changes only apply to the intended element.

This example demonstrates how to style a simple card component modularly.

CSS Modules in React

Modern frontend environments such as React and Next.js offer native support for CSS Modules. This allows component-level styles where class names are automatically made unique.

This example shows the modular styles of a button component with different variations.

Tips for CSS Modules

Some advice to use CSS modules effectively.

• Always name classes consistently so they are easily recognizable.
• Keep modules small: one module should belong to one component.
• Combine modules with architecture (e.g., BEM + Modules) for a clearer project.
