About This Tool
The CSS Formatter cleans up minified, compressed, or inconsistently formatted CSS stylesheet code, structuring rules with clear line breaks and indentation.
When maintaining third-party stylesheets, debugging production asset bundles, or reviewing pull requests, unformatted single-line CSS is difficult to read and error-prone to edit.
### How the CSS Formatter Works 1. Declaration Separation: Breaks grouped semicolon-separated property declarations onto individual indented lines. 2. Rule Block Indentation: Opens CSS selector declaration blocks on fresh lines with standardized two-space indentation. 3. Closing Brace Formatting: Closes selector blocks with dedicated line breaks to clearly delineate adjacent CSS rule sets.
### Concrete Formatting Example Paste compressed stylesheet input: `body{margin:0;padding:0;background-color:#fff;} h1{font-size:24px;color:#333;}`
The formatter outputs structured readable CSS: ```css body { margin:0; padding:0; background-color:#fff; } h1 { font-size:24px; color:#333; } ```
### Processing and Privacy All string transformations execute in-browser via local JavaScript. No stylesheets, style rules, or design assets leave your computer.

Frequently Asked Questions
Does formatting CSS affect stylesheet behavior or specificity?
No. The formatter only adjusts whitespace, indentation, and line breaks. It preserves all selectors, properties, values, and cascade rules unchanged.
Can this tool format SCSS or LESS code?
It formats standard CSS selector blocks and properties. Nested preprocessor syntax with custom mixins may require specialized preprocessor linters.
Are my project stylesheets sent to an external server?
No. All CSS formatting runs locally in your browser memory.
