Frequently Asked Questions

Why should I minify CSS?

Minifying CSS reduces file size, improves loading speed, and optimizes bandwidth usage. This leads to better website performance and lower hosting costs.

Is minified CSS harder to maintain?

No, you should maintain your original, formatted CSS files and only use minified versions for production. This ensures code readability during development.

What about source maps?

While this tool doesn't generate source maps, you can use build tools like webpack or gulp for source map generation when minifying CSS in your development workflow.

Will minification break my CSS?

No, proper minification preserves the functionality of your CSS while removing unnecessary characters. Always test minified CSS in a staging environment before deployment.
