A modular minifier, built on top of the PostCSS ecosystem.
cssnano is a modern, modular compression tool written on top of the PostCSS ecosystem, which allows us to use a lot of powerful features in order to compact CSS appropriately.
Our preset system allow you to load cssnano in a different configuration depending on your needs; the default preset performs safe transforms, whereas the advanced preset performs more aggressive transforms that are safe only when your site meets the requirements; but regardless of the preset you choose, we handle more than whitespace transforms!
Optimisations range from compressing colors & removing comments, to discarding
overridden at-rules, normalising unicode-range descriptors, even mangling
gradient parameters for a smaller output value! In addition, where it's made
sense for a transform, we've added Browserslist
to provide different output depending on the browsers that you support.
For further details check out the website:
You can now try cssnano online!
