CSS Formatter

The CSS Formatter standardizes the appearance of CSS code by enforcing consistent indentation, line wrapping, and property ordering. It targets frontend developers, build engineers, and design-system teams who require reproducible formatting across projects and languages. By producing deterministic output, it reduces cognitive load during reviews and accelerates onboarding for new contributors.
Conceptually, the tool parses input CSS into an abstract syntax tree and applies formatting rules without altering the underlying selectors, properties, or values. It can preserve comments and string literals, reflow multi-line blocks, and wrap long rules according to a maximum line length, yielding a stable, deterministic result.
Core features include adjustable indentation (2 or 4 spaces or tabs), optional minification, and optional property sorting. Advanced options support max line length, selective rule grouping, and optional alignment of selectors. The tool supports common CSS, at-rules, media queries, and modern CSS constructs while remaining faithful to valid CSS syntax.
Typical use cases include preparing code for pull requests, enforcing team standards, integrating into CI pipelines, or migrating codebases to a unified style. The formatter operates on CSS text, making it suitable for code editors, build steps, or automated QA checks, and it can be combined with a minifier for production builds.
