Questions
How do I beautify minified CSS?
Paste your minified or compressed CSS into the input and the formatter will add proper line breaks, indentation, and spacing around selectors, properties, and values for easy readability.
What indentation style does the CSS formatter use?
The formatter uses a standard 2-space indentation by default, placing each CSS property on its own line and adding a space after colons and before opening braces for consistent, readable output.
Is it safe to paste my CSS into this formatter?
Yes, the CSS formatter runs entirely in your browser. No data is sent to any server, so your stylesheets stay private.
Does the CSS formatter handle media queries and nested selectors?
Yes, the formatter correctly indents media queries, keyframe blocks, and nested selectors while keeping each declaration on its own line.
Can I format SCSS or LESS with this tool?
The tool is designed for standard CSS. SCSS and LESS files may partially format since they share similar syntax, but preprocessor-specific features like variables and mixins may not indent perfectly.
