|
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].
