CSS Minification for Production
CSS minification removes whitespace, comments, redundant semicolons, and shortens color values (#ffffff → #fff) without changing styling behavior. Minified CSS reduces file size by 20-40%, decreasing page load time and bandwidth costs. Always keep unminified source for editing — minified output is not human-readable. CDN caching amplifies the benefit: a 40KB saving on a file served 100,000 times saves 4GB of bandwidth.
