CSS Formatter

The tool parses input CSS and outputs a consistently formatted version according to selected style rules. It preserves comments and strings while restructuring whitespace, braces, and semicolons for readability. It is designed for developers who enforce a style guide, code reviewers seeking reduced diffs, and teams aiming for uniform CSS across projects.
Internally, a CSS parser builds an AST, then a rewriter applies indentation, line breaks, and property grouping. Users select a format: expanded, compact, or minified, and may configure indent size and maximum line length. The system can also sort properties or preserve original order to align with team conventions. The result is deterministic given the same inputs and options, suitable for PRs and automated checks.
This tool emphasizes formatting quality over semantic changes; it does not transform SCSS/LESS syntax or resolve vendor-prefixed properties beyond standard CSS semantics. It benefits frontend teams by improving readability, making diffs smaller, and accelerating onboarding for new contributors. The formatter supports common CSS constructs such as selectors, declarations, blocks, and at-rules like @media, while maintaining proper nesting and braces structure in a consistent manner.
