What is CSS Minification?
Definition
Minification is the process of removing unnecessary characters from code (whitespace, comments, line breaks) without changing its functionality. CSS minification can reduce file size by 20-50%, while JavaScript minification also shortens variable names.
Why It Matters
Minified files load faster because they are smaller, reducing bandwidth and improving page speed scores. Google uses page speed as a ranking factor, so minification directly impacts SEO. All production websites should serve minified CSS and JavaScript.
