FAQ
- Does the formatter change attribute order?
- No. It only adjusts whitespace, indentation, and line breaks while preserving attribute order.
- Can I format embedded CSS or JS?
- Inline scripts and styles stay untouched by default. Enable aggressive mode to force additional spacing if needed.
- Is my HTML sent to a server?
- Everything runs locally via the js-beautify library—your markup never leaves the browser.
