Frequently Asked Questions
What happens if my CSS has unbalanced braces?
The tool reports an error naming the problem instead of producing broken output. Fix the braces and try again.
Does formatting change my styles?
No. It only changes whitespace, line breaks and indentation. Selectors and declarations stay the same.
Can it format minified CSS?
Yes — that is its main use. Paste minified CSS and get readable, indented code back.
Is my CSS uploaded anywhere?
No. Formatting runs entirely in your browser.
