Computers don't care about spaces, comments, or nice indentation. Humans do. When you write code, you make it readable. But all that whitespace adds file size.
"Minification" is the process of stripping out everything a computer doesn't need. It turns a beautiful 50KB file into an ugly, fast 20KB file.
Does Size Matter?
Yes. If your CSS file is 200KB, a person on a 3G mobile network has to wait an extra 2 seconds for your site to look right. In 2026, nobody waits 2 seconds. They hit "Back."
The Impact:
Minifying can reduce file size by 30-50%. This directly improves your LCP (Largest Contentful
Paint) scores in Core Web Vitals.
How to Do It
You don't do this manually. It would take forever. You use a tool.

Bonus Tip: GZIP
Minification + Server Compression (GZIP/Brotli) = Blazing fast sites. Check if your host enabled GZIP.
