FAQ
Does it reorder properties?
Formatting keeps logical order; minify doesn’t reorder. For deep normalization across files, combine this tool with XML/HTML formatters depending on context.

Yes, vendor prefixes remain intact.
SASS/LESS supported?
Paste compiled CSS. Use your build tools to compile SASS/LESS to CSS, then format/minify here.
