Frequently Asked Questions
QHow much does minifying reduce file size?
Typically 10–30% depending on how much whitespace, comments, and formatting the original file had. The exact savings vary by source file.
QDoes minifying change how the CSS behaves?
No — minification only removes characters that don't affect rendering (whitespace, comments, redundant semicolons). The visual output is identical.
QShould I minify CSS during development?
No — keep readable CSS during development and minify only as a build step before deploying to production.
