STYLUS/LESS Conversion

Tool Introduction

This tool is a free online STYLUS to LESS code converter. It helps front-end developers and designers quickly and accurately convert style code written in Stylus syntax to LESS syntax. Whether for project technology stack migration, unifying preprocessors in team collaboration, or learning and comparing the syntax of two CSS preprocessors, this tool provides great convenience, simplifying the code conversion process and improving development efficiency.

How to Use

1. Paste the Stylus style code you need to convert into the input box on the left side of the tool. Please ensure the pasted code is complete and syntactically correct Stylus code.
2. After confirming the input is correct, click the “Convert” button on the page.
3. The converted LESS code will automatically appear in the output box on the right. You can directly copy this LESS code into your project.
4. To clear the current input and perform a new conversion, click the “Clear” button.

Frequently Asked Questions

• Q: Which Stylus features does this tool support for conversion?
• A: This tool supports most common Stylus features, including variables, mixins, nested rules, function calls (e.g., darken(), lighten()), operators, and basic selectors. For a very small number of highly Stylus runtime-dependent or LESS-unsupported specific advanced syntaxes, manual adjustments may be required.
• Q: Is the output LESS code format standardized?
• A: This converter generates standard-format LESS code, usually with curly braces and semicolons, maintaining good readability and compatibility with standard LESS compilers.
• Q: What if Stylus code conversion fails or the result is incorrect?
• A: First, please check if your Stylus input code conforms to Stylus syntax specifications. If the code is correct but issues still arise, it might be because the Stylus code uses specific advanced features not supported by LESS, or there are edge cases in syntax conversion. It is recommended to try simplifying the relevant code or making minor manual adjustments.
• Q: Can this tool convert Stylus's “bare” properties (Indented Syntax)?
• A: Yes, this tool can convert Stylus's indented syntax (e.g., without semicolons and parentheses) into LESS's standard syntax (with curly braces and semicolons).

Notes

• Please ensure that the input Stylus code is syntactically correct; otherwise, it may lead to conversion failure or incorrect LESS code generation. Syntactically incorrect code may not be parsed correctly.
• Although this tool strives to maintain the accuracy and completeness of the conversion, Stylus and LESS may have subtle differences in some advanced features, built-in function names, or syntactic sugar. After conversion, it is recommended that you carefully review the generated LESS code and make any necessary fine-tuning or optimization according to actual project requirements.
• Converting a large amount or very complex Stylus code may take a little longer; please wait patiently for the conversion to complete.
• This tool only performs code syntax-level conversion and does not involve Stylus's runtime compilation logic or Stylus-specific AST (Abstract Syntax Tree) operations.
• This tool does not save any user input data, protecting your code privacy.
