CSS Modules is a specification and tooling ecosystem for CSS files in which all class and animation names are locally scoped by default, compiling to the ICSS interchange format. It integrates with bundlers like webpack so styles can be imported into JavaScript components as objects mapping local to global class names.

Use cases

• scope css class names to avoid collisions
• import css styles into react components
• compose reusable css classes across modules
• prevent global style leakage in large projects
• theme components with locally scoped css

When to choose

• building component-based frontend apps where style isolation matters
• using webpack or similar bundlers with css loader support
• wanting modular, reusable css without a css-in-js runtime

When to avoid

• need a full utility-first or component css framework with prebuilt styles
• project has no bundler or build step to process css modules
• prefer plain global stylesheets for simple static sites
