Generate documentation and style guides with design patterns from stylesheets.


StyleDocco generates documentation and style guide documents from your stylesheets.

Stylesheet comments will be parsed through Markdownand displayed in a generated HTML document. You can write HTML code prefixed with 4 spaces or between code fences(```) in your comments, and StyleDocco show a preview with the styles applied, and displays the example HTML code.

The previews are rendered in a resizable iframes to make it easy to demonstrate responsive designs at different viewport sizes.

Suggestions, feature requests and bug reports are welcome either at GitHubor on Twitter (@jacobrask).


StyleDocco requires Node.js. After installing Node.js, run npm install -fg styledoccoor clone this repository and run ./bin/styledocco.

StyleDocco is free and open source software, released under the MIT license.

/* Provides extra visual weight and identifies the primary action in a set of buttons.

    <button class="btn primary">Primary</button> */
.btn.primary {
    background: blue;

Would display the description, a rendered button as well as the example HTML code. The CSS will be applied to the preview.

See the examplesfolder for more in-depth examples.

Tips and tricks

  • StyleDocco will automatically compile any SASS, SCSS, Less or Stylus files before they are applied to the page. You can also enter a custom preprocessor command if you want to pass custom parameters to the preprocessor.
  • If your project includes a README.mdfile, it will be used as the base for an index.html.
  • If you don't specify a custom name, StyleDocco will use the name from a package.jsonfile if it finds one.
  • Put some whitespace before a comment block to exclude it from the documentation.
  • Level 1 headings will automatically create a new section in the documentation.
  • Add :hover, :focus, etc as class names in example code and the pseudo class styles will be applied in the preview.
