Technology
CSS Modules is a development technology used to build, support, or power modern software applications and digital products.
CSS Modules provide locally scoped CSS class names for component-based applications. During the build process, class names are transformed so styles are associated with a specific module rather than being globally available. This helps reduce naming collisions while keeping the familiar CSS syntax. CSS Modules are commonly used in React, Next.js, and other frontend projects where teams want component-level style isolation without adopting a CSS-in-JS solution.
For projects using CSS Modules, teams should consider the application's requirements, expected scale, integration points, deployment environment, testing approach, and long-term maintenance. Choosing the technology should also take into account the existing skills of the development team and the libraries or services already used by the product.
