Stylus to CSS: Core Features and Principles

Stylus preprocessor syntax used in front-end development cannot run directly in browsers. This tool parses Stylus features like indentation-based nesting, variables, and mixins to generate W3C-compliant CSS code. The conversion process preserves your original comment structure, automatically converting single-line // comments into the /* */ format.

FAQ

Will comments be lost during the Stylus to CSS conversion?
No, single-line // comments are automatically converted to the /* */ format.

Does the converted CSS require additional processing?
The output is standard CSS2.1/3 syntax, but please note: 1) Some vendor prefixes may need to be added manually. 2) Deep nesting can generate redundant selectors.

Important Notes

Before converting, please check: 1) Indentation must be consistent (spaces or tabs). 2) Variables must be defined before use. 3) Mixins cannot contain undefined parameters.

Technical Notes & Best Practices

Typical conversion example: Inputting .btn &-primary color: $blue will output .btn-primary { color: #007bff; }. We recommend keeping your original .styl files during development for easier maintenance.
