Frequently Asked Questions

The tool formats standard CSS. SCSS and LESS may partially work since they're syntactically similar, but nested rules and variables may not format perfectly. For SCSS/LESS, dedicated tools like Prettier with SCSS support are recommended.

When enabled, comma-separated selectors are placed on separate lines. For example, "h1, h2, h3 { }" becomes each selector on its own line, improving readability in long selector lists.

Yes. Select "Tab" in the Indent Size dropdown to use tab characters instead of spaces. This is a common preference in projects using tab-based indentation.

No. Beautifying only adds/adjusts whitespace and newlines. It does not reorder properties, change values, add vendor prefixes, or modify the CSS in any functional way. The output is semantically identical to the input.
