How to use the CSS Formatter
- Paste your CSS.
- Press Format.
- Copy the beautified stylesheet.
- Adjust and re-format as you edit.
How it works
Rules and declarations are spaced and indented consistently. The formatter does not evaluate styles in a browser engine—it only rewrites text layout.
Useful before code review or when reading minified CSS.
Examples
- body{margin:0;color:#333} becomes multi-line with indentation.
- Nested rules (if present) are indented by depth where supported.
- Comments are preserved when the formatter keeps them.
