- > A modular minifier, built on top of the [PostCSS] ecosystem.
- [][ci] [](https://ci.appveyor.com/project/ben-eb/cssnano/branch/master) [](https://coveralls.io/github/ben-eb/cssnano?branch=master) [][npm] [][deps] [](https://gitter.im/ben-eb/cssnano?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
- cssnano is a modular minifier that aims to utilise small modules from the
- PostCSS ecosystem, rather than being an all-encompassing module that may be
- difficult to contribute to. Because it is written on top of PostCSS, it is able
- to do more than simple whitespace transforms - including advanced optimisations
- such as custom identifier reduction, `z-index` rebasing, and adjacent selector
- merging.
- Note that cssnano enables aggressive optimisations by default, which might not
- always be what you want. Set `options.safe` to `true` if you want to disable
- this. In future versions, only safe options will be enabled by default, starting
- from [version 4][v4].
- For further details check out the [website](http://cssnano.co/):
- * [Installation guide for your build process](http://cssnano.co/usage/).
- * [Full list of optimisations](http://cssnano.co/optimisations/).
- * [Customise the output (options documentation)](http://cssnano.co/options/).
- You can now [try cssnano online](https://runkit.com/npm/cssnano) via Runkit!
