CSS specifications are often still in flux and various parts might change or disappear altogether.
Specifications also contains parts that haven't been implemented yet in a browser.
Only CSS that is widely adopted can be expected to be stable.

The next` grouping contains a combination of what is currently valid in browsers and the progress in various specifications.

_In the future more groupings might be added._
