Frequently Asked Questions

What Stylus features are converted?

Stylus syntax (indentation-based, optional braces/semicolons, variable $prefix) is converted to standard CSS with braces, colons, and proper nesting expansion.

Does it handle Stylus variables?

Yes. Stylus variables (varName = value) are converted to CSS custom properties (--var-name: value) or hardcoded values depending on the use case.

Does it support Stylus mixins?

Basic mixin expansion is supported. Complex Stylus-specific features like conditionals and loops may require manual conversion.

Can I convert back from CSS to Stylus?

Use the CSS to Stylus Converter tool for the reverse direction, which adds Stylus-style indentation and syntax.

Is my Stylus data stored?

No. All conversion happens locally in your browser. No Stylus data is transmitted.
