CSS Modules
CSS Modules is a CSS file in which all class names and animation names are scoped locally by default, preventing style conflicts in large applications. It works by automatically generating unique class names during the build process, ensuring that styles are encapsulated within individual components. This approach is commonly used in modern JavaScript frameworks like React and Vue to manage CSS in a modular and maintainable way.
Developers should use CSS Modules when building component-based applications where style isolation is critical to avoid naming collisions and improve code maintainability. It is particularly useful in large-scale projects with multiple developers, as it allows for local scoping without relying on naming conventions like BEM. CSS Modules integrate seamlessly with build tools like Webpack, making it a practical choice for modern front-end development workflows.
