Frequently Asked Questions
What's the difference between beautify and minify?
Beautify adds line breaks, indentation, and spacing to make CSS readable and maintainable. Minify removes all unnecessary characters to create the smallest possible file size for faster page loads.
Does this tool validate CSS?
This tool focuses on formatting and beautification. It doesn't perform strict CSS validation. For comprehensive validation, use the W3C CSS Validation Service.
Will CSS comments be preserved?
Yes, when using beautify. Comments are kept to maintain documentation. The minify option removes comments to reduce file size.
Can I format Sass or SCSS?
This tool is designed for standard CSS. While it may handle some Sass/SCSS syntax, advanced features like mixins, variables, and nesting may not format correctly. Use a Sass-specific formatter for those.
Does it support CSS preprocessors?
This tool works best with standard CSS. For preprocessor syntax (Less, Sass, Stylus), use a formatter designed for those languages, or compile to CSS first and then beautify.
