Frequently Asked Questions
What is CSS minification?
CSS minification is the process of removing unnecessary characters from CSS code (whitespace, comments, line breaks) without changing its functionality, reducing file size for faster page loading.
Does minifying CSS affect functionality?
No. Minification only removes cosmetic characters. The CSS rules, selectors, and properties remain exactly the same.
How much can CSS minification reduce file size?
Typically 20-40% depending on the original formatting. Heavily commented and indented files can see even greater reductions.
