Frequently Asked Questions
Does formatting change how CSS works?
No. Whitespace in CSS is ignored (outside strings). Formatting only affects readability — the styles render identically.
Can I minify CSS too?
Yes. CipherKit's formatter includes a minify option that removes all whitespace, producing the most compact CSS for production use.
Does this validate CSS syntax?
The formatter catches some syntax errors during parsing. For comprehensive validation, use a dedicated CSS validator.
