Reviewing formatted stylesheets
Readable selectors, blocks, and declarations help when tracing cascade conflicts or reviewing a stylesheet. This formatter parses common CSS syntax and prints it with consistent indentation.
CSS preprocessors and experimental syntax may need a matching parser or project-specific configuration. For Sass, Less, or framework-specific styles, use your project's formatter and configuration when available.
