Frequently Asked Questions
Does formatting change how HTML renders?
Usually no. Extra whitespace between tags is typically ignored. However, whitespace inside text nodes and pre/code elements is preserved and may affect display.
Can I minify HTML too?
Yes. CipherKit's formatter includes a minify option that removes unnecessary whitespace for production use.
Does this validate HTML?
The formatter catches some syntax errors during parsing. For comprehensive validation, use a dedicated HTML validator like W3C's.
