</div>

cssnano is a modern, modular CSS compression tool written on top of the PostCSS
ecosystem, which allows us to use a lot of powerful features in order to minify
CSS.

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 colours & 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](https://github.com/ai/browserslist)
to provide different output depending on the browsers that you support.

For further details check out the [website](https://cssnano.github.io/cssnano):

- [Installation guide for your build process](https://cssnano.github.io/cssnano/docs/getting-started).
- [Full list of optimisations](https://cssnano.github.io/cssnano/docs/what-are-optimisations/).

You can now [try cssnano online](https://cssnano.github.io/cssnano/playground/)!
