CSS Formatter
Pretty-print CSS locally in your browser with 2- or 4-space indent.
Tool workspace
Pretty-print CSS in your browser. Styles are not injected or executed. Nothing you paste is uploaded. Best-effort formatting — not a full CSS validator.
How it works
Paste CSS, choose an indent size (2 or 4 spaces), then Format.
Formatting runs entirely in your browser with a best-effort brace-aware prettifier. Styles are never injected into the page, executed, or uploaded. Remote @import URLs are not fetched.
Empty input clears the result—no error. This is not a full CSS validator or browser-equivalence checker.

Examples
- body{margin:0} → indented rules
- Nested @media blocks → readable structure
- Indent size 4 → wider indentation
