About CSS Formatter
CSS formatting normalizes indentation, declaration spacing, and brace placement. The minifier removes comments and collapses whitespace where the parser doesn't care.
This tool runs js-beautify locally. Multi-thousand-line stylesheets format instantly, and your code never leaves the page.

Frequently asked
Is my CSS sent to a server?
No. js-beautify runs in your browser. Nothing leaves your device.
Does it preserve at-rules and nested selectors?
Yes. Media queries, keyframes, and nested selectors are formatted with proper indentation.
What about minification?
Strips comments, collapses whitespace, removes redundant semicolons. Lossless transformations only.
Can it handle SCSS or Less?
It handles plain CSS reliably. SCSS-specific syntax (variables, mixins) may not format ideally.
