Frequently Asked Questions

Does minification change how CSS works?

No. Minification only removes whitespace and comments. The CSS rules and their effects remain identical.

Is my code sent to a server?

No. CSS minification is handled by JavaScript string operations running in your browser. Your stylesheet source is processed entirely locally — no CSS code is transmitted to any external service.
