Frequently Asked Questions
How much does minification save?
Typically 20-40% file size reduction, sometimes more if CSS has many comments and whitespace. Combined with gzip, total savings can exceed 80%.
Should I minify during development?
No, keep CSS readable during development. Minify only for production builds. Most build tools (Webpack, Vite) handle this automatically.
Does minification change how CSS works?
No, minified CSS is functionally identical. Only whitespace, comments, and unnecessary characters are removed. Selectors and properties remain the same.
