CSS to Stylus Converter - Convert CSS to Stylus Online

The CSS to Stylus Converter turns standard CSS into Stylus syntax in your browser. It keeps the original styling logic while removing braces and semicolons, and it can optionally nest related selectors to make styles easier to read and maintain.

What this tool does

Parses valid CSS and converts declarations into Stylus property format.
Optionally transforms related selectors into nested Stylus blocks.
Preserves common at-rules such as @media.
Supports direct paste, sample loading, copy, and download workflow.

Why convert CSS to Stylus?

Stylus syntax is concise and expressive, which helps reduce boilerplate in larger stylesheets. Teams often use this conversion while migrating legacy CSS or preparing styles for a Stylus-based build pipeline.

Example conversion

Input CSS

.button {
  padding: 12px 16px;
  color: #fff;
}

.button:hover {
  color: #e5e7eb;
}

Output Stylus

.button
  padding 12px 16px
  color #fff

  &:hover
    color #e5e7eb

How the conversion works

CSS is parsed into an abstract syntax tree.
Selectors and declarations are extracted and normalized.
Declarations are rewritten in Stylus syntax.
When enabled, related selectors are grouped into nested blocks.

Frequently Asked Questions

Is this tool safe for private CSS code?

Yes. Conversion runs in the browser, so your CSS content stays on your device during normal use.

Does this converter support media queries?

Yes. Standard at-rules such as @media are preserved in the Stylus output.

Why does output sometimes look different from my selector order?

If nesting is enabled, selectors may be grouped under parent selectors for readability. Disable nesting to keep a flatter output structure.
