CSS Modules is an approach to writing CSS that scopes styles to a specific component, module, or section of a web page. With CSS Modules, styles are locally scoped by default, which means that the styles defined for one component or module won’t affect other parts of the page.
Here are some of the benefits of using CSS Modules:
- Avoiding naming conflicts: By locally scoping styles, CSS Modules prevent naming conflicts that can occur when different components or modules use the same class names.
- Improved maintainability: CSS Modules allow developers to organize styles more effectively by grouping them according to the components or modules they belong to. This makes it easier to find and update styles when necessary.
- Better code reusability: By making styles specific to a component or module, CSS Modules encourage code reusability. Developers can easily move components or modules between projects without worrying about their styles affecting other parts of the page.
- Improved performance: With CSS Modules, only the styles required for a specific component or module are loaded. This helps to reduce the size of the CSS file and improve page load times.
To use CSS Modules, you need a build tool or preprocessor that supports it, such as Webpack or PostCSS. With these tools, you can configure your build process to generate unique class names for each component or module, ensuring that the styles are locally scoped.
