Frequently Asked Questions

Is my CSS code secure?
Yes! All CSS processing happens entirely in your browser. Your code is never uploaded to any server.
Does this tool validate CSS syntax?
The formatter processes your CSS and will show errors if the syntax is invalid. It helps identify common issues like missing semicolons or brackets.
What's the difference between Beautify and Minify?
Beautify adds proper indentation and line breaks for human readability. Minify removes all unnecessary whitespace to create the smallest possible file size for production use.
Can I format CSS with vendor prefixes?
Yes! The formatter handles all CSS including vendor prefixes (-webkit-, -moz-, -ms-) and modern CSS features.
Does it support CSS preprocessor syntax?
This tool is designed for standard CSS. For SASS or LESS, you'll need to compile them to CSS first.
