Frequently Asked Questions
What does CSS minification remove?▾
It removes whitespace, comments, unnecessary semicolons, and shortens color codes (e.g., #ffffff → #fff) without changing behavior.
Will my CSS still work after minification?▾
Yes. Only cosmetic formatting is removed — all selectors, properties, and media queries remain functionally identical.
Should I minify CSS for production?▾
Absolutely. Minified CSS loads faster, reducing page load times. Most build tools (Webpack, Vite) do this automatically.
