Does it support CSS variables and modern CSS?

Yes. The formatter treats CSS as text with structural rules (braces, colons, semicolons), so it handles CSS variables, calc(), custom properties, and any modern CSS syntax correctly.

Is my data uploaded to a server?

No. All formatting runs locally in your browser using JavaScript. Your CSS never leaves your device.

Will it break vendor-prefixed properties?

No. Vendor prefixes (-webkit-, -moz-, -ms-) are treated like any other property and formatted normally.

Can I beautify SCSS or Less?

Basic SCSS and Less files without complex mixins or loops will format correctly since they share the same brace-and-property structure as standard CSS.

Why Beautify CSS?

Minified CSS is compressed for production delivery but is nearly impossible to read or edit. The CSS Beautifier expands it back into readable form with consistent indentation, one property per line, and proper spacing around braces and colons — making debugging and review much faster.

What Gets Formatted

Element	Formatting applied
Selectors	Each selector on its own line, opening brace on same line
Properties	One property per line, indented
Values	Space after colon, semicolon at end
Media queries	Inner rules indented an extra level
Comments	Preserved on their own line

Beautify vs Minify

Use the CSS Beautifier during development for readable code. Before deploying, use the CSS Minifier to strip whitespace and reduce file size for faster page loads.
