Frequently Asked Questions

The formatted CSS is larger — does it hurt page load?
No. Formatting is for development and debugging; ship the minified output in production. The two are lossless inverses. This tool offers both expanded and compact modes: expanded while developing, minified for build artifacts.
Why did the property order change?
If sorting is enabled, properties are grouped by category (layout → box model → typography → visuals), a maintainability convention popularized by stylelint-order. In plain formatting mode the original order is preserved.
Does it support CSS nesting (&)?
Yes. Formatting only adjusts whitespace and line breaks without interpreting properties, so native CSS nesting as well as Less and SCSS structures expand fine. Minify mode keeps nesting intact rather than flattening it.
