CSS Formatter & Beautifier

Format, beautify, and minify CSS code. Instantly prettify your stylesheets with proper indentation and clean structure.

How It Works

This tool parses your CSS input using a custom tokenizer and reformats it with proper indentation. All processing happens entirely in your browser — no data is sent to any server.

• Format — parses the CSS and re-indents it with consistent spacing (2 spaces, 4 spaces, or tabs)
• Minify — removes all unnecessary whitespace and comments to produce the smallest possible output
• Syntax Highlighting — the output uses color-coded highlighting for selectors, properties, values, at-rules, and comments

About CSS

CSS (Cascading Style Sheets) is a stylesheet language used to describe the presentation of a document written in HTML or XML. It controls layout, colors, fonts, spacing, and responsiveness of web pages across different devices and screen sizes.

Formatting Rules

• Each selector is placed on its own line
• Opening braces appear on the same line as the selector
• Each property declaration is placed on its own line with indentation
• A space is added after each colon in declarations
• Each declaration ends with a semicolon
• Closing braces are placed on their own line at the original indent level
• Nested rules (media queries, keyframes) receive additional indentation

Common Use Cases

• Debugging — read minified CSS from production builds or third-party libraries
• Code Review — standardize indentation and formatting before reviewing changes
• Learning — understand the structure of complex stylesheets with nested media queries
• Optimization — minify CSS to reduce file size for production deployment
