About CSS Beautifier

Format CSS with consistent indentation.

The CSS beautifier tokenizes your stylesheet into selectors, declarations, at-rules, and comments. It then reformats the output with each selector on its own line (for multi-selector rules), each property-value pair on a separate line with consistent indentation, and standardized spacing around colons, braces, and semicolons. Nested at-rules like @media receive additional indentation levels to clearly show the stylesheet's structure.

Use the left editor to enter your data. The output updates in real time. You can copy, clear, download, or expand either pane.

FAQs

Does the CSS beautifier handle media queries and nested at-rules?

Yes. The beautifier correctly indents content within @media, @supports, @keyframes, and other at-rules. Nested selectors within media queries are indented an additional level for clear visual hierarchy.

Can I format minified CSS from a production stylesheet?

Absolutely. Paste any minified or compressed CSS and the beautifier will reconstruct proper formatting with one property per line, consistent indentation, and spaces after colons and before opening braces. This makes production CSS readable for debugging.

Does the beautifier sort CSS properties?

The beautifier focuses on formatting — adding whitespace, indentation, and line breaks — without reordering properties. Your property order is preserved exactly, so authored groupings and intentional cascading order remain intact.

Can I format CSS that includes vendor prefixes?

Yes. Vendor-prefixed properties (-webkit-, -moz-, -ms-, -o-) are formatted the same as standard properties. Each prefixed declaration gets its own line with proper indentation for easy scanning.

Does the CSS formatter handle SCSS or LESS syntax?

The beautifier is designed for standard CSS syntax. While it may partially format SCSS or LESS files since they are CSS supersets, features like nesting, variables ($var, @var), and mixins may not format perfectly. Use a dedicated SCSS/LESS formatter for those.
