Frequently Asked Questions
What does CSS minification remove?
It removes comments, whitespace, newlines, and unnecessary semicolons. It may also shorten color values (e.g., #ffffff to #fff) and remove redundant units.
Can minification break my CSS?
Proper minification should never break CSS. However, some advanced minifiers may combine selectors or remove unused rules, which could cause issues if not configured correctly.
Should I use minified CSS during development?
No, keep your CSS readable during development. Use build tools to automatically minify for production. Consider source maps for debugging production issues.
