CSS minification removes whitespace, comments, line breaks, and shortens color codes (#ffffff → #fff) to reduce file size without changing functionality.

No! The [CSS Minifier](/tools/css-minifier/) only removes whitespace and comments that browsers ignore. All CSS rules, properties, and values remain intact.
