Sometimes it is not enough to just prefix a property, but you also need to prefix the value or even transform the property and value completely. Plugins are used to tackle browser incompatibilities. File an issue or submit a PR if a plugin you need is missing (these are roughly equivalent to Autoprefixer's hacks). The following plugins are included by default:
Adds support for prefixed calc values on any property.
Adds support for prefixed new cursor values zoom-in and zoom-out.
Adds support for prefixed new cursor values grab and grabbing.
Adds support for prefixed display values using display: flex or display: inline-flex.
Adds trasformators for the early 2012 flexbox specification used in IE 10 and IE Mobile 10.
Adds trasformators for the old 2009 flexbox specification used in old Webkit-based browsers.
Adds support for prefixed background and backgroundImage values linear-gradient, radial-gradient, repeating-linear-gradient and repeating-radial-gradient.
Adds support for prefixed maxHeight, maxWidth, width, height, columnWidth,minWidth, minHeight intrinsic & extrinsic sizing values min-content, max-content, fill-available, fit-content, contain-floats
