Frequently Asked Questions

CSS Modules automatically scope class names by appending a unique hash, so styles never leak to other components. They are widely used with React, Vue, and other frameworks to avoid global style conflicts and simplify long‑term maintenance.

Scoped CSS adds a custom data attribute (e.g., data-scope-abc123) to every selector and requires the same attribute on the corresponding HTML element. This way the style is applied only to elements that carry that exact attribute, effectively isolating the style without renaming classes.

Yes. You can change the hash length (4‑8 characters) and the separator between the original name and the hash. You can also add a custom prefix or suffix to fit your project’s naming conventions.

Absolutely! It runs entirely in your browser – no data is ever sent to a server. Use it as much as you like, completely free.

For CSS Modules (React/Angular/Vite) you would import the styles object and reference the generated class names. For scoped CSS you can copy the output CSS and manually add the scope attribute to your HTML. Many frameworks also support build‑time scoping.
