px is an absolute unit. rem is relative to the root font size (usually 16px). Using rem makes layouts scale properly when users change their browser's default font size, which is important for accessibility.
Typically 20–40% reduction by removing whitespace, comments, and redundant semicolons. Combined with gzip compression on the server, minified CSS can be 70–80% smaller than the original.
