Convert CSS to Stylus syntax. Part of the DevTools Surf developer suite. Browse more tools in the CSS collection.

Use Cases

• Node.js developers using Stylus with Express or Koa projects
• Teams wanting the most minimal CSS preprocessor syntax
• Developers converting CSS for projects already using Stylus
• Frontend devs preferring Python-like indentation-based styling

Tips

• Verify that optional colons and semicolons are properly stripped
• Check that CSS functions convert to Stylus built-in equivalents
• Review converted mixins for Stylus's transparent mixin syntax

Fun Facts

• Stylus was created by TJ Holowaychuk in 2010, the same developer who created Express.js for Node.js.
• Stylus is the most flexible CSS preprocessor, allowing you to omit colons, semicolons, braces, and even the comma in selectors.
• Stylus has a unique 'transparent mixin' feature where regular properties can be overridden to act as mixins automatically.

FAQ

What makes Stylus different?

Stylus is the most flexible of the four: braces, colons, and semicolons are all optional. It has first-class arithmetic and transparent mixins. The tradeoff is less tooling and a smaller community.

Is Stylus still maintained?

Barely — the last major release was years ago. Use only for legacy projects. SCSS is the safer bet for new work.

Does the converter keep my selectors?

Yes — every CSS selector is preserved 1:1. Stylus just strips the required syntax, so the same rules apply.

Can I write Stylus without braces?

After conversion, yes. The output uses the minimal Stylus style (no braces, no semicolons) by default — toggle if you want CSS-like syntax.
