Does CSS minification affect styling rules or animations?

No. Minification only strips extraneous comments, tabs, line breaks, and unnecessary spaces around colons and braces. All style selectors, media queries, and keyframe animations render identically.

How much file size reduction can I expect from CSS minification?

Unminified CSS with comments and formatting typically sees 30% to 55% raw reduction, speeding up CSSOM parse times.
