gulp-crass-minifier

Gulp plugin wrapping the Crass CSS optimizer for advanced CSS minification via full CSS parsing, enabling optimizations like redundant rule elimination and property merging that string-based minifiers cannot achieve. Version 1.0.0 depends on Crass, which carries a known security vulnerability (GitHub issue #77) making it unsafe for production environments. The plugin is in maintenance mode; it has no recent updates and a TODO list for tests. It supports custom options for prettification, optimization levels, CSS4 features, and browser targeting. Consider faster, safer alternatives like cssnano or clean-css.
