Draft and PR a CSSWG note

[argyleink]

Using Bikeshed, draft a document that could look a lot like this 2017 snapshot. It should:

• enumerate each CSS feature under a heading
• point to the community group and provide a high level introduction to the purpose
• have an area for endorsements

Goal is to be a publicly visible, CSSWG official article, on CSS4, CSS5 and beyond. This document should aid in adoption by pacifying concerns about "is this sanctioned or official."
