To review and/or to understand the #CSS levels, read this #explainer 😉:
Replying to @w3cdevs
All current #CSS specs have their own specific levels ranging from 1 to 5, but CSS as a whole does not have a version. Two reasons: 1) some features are easier to complete than others, 2) CSS became so big that it is too much work for the editors to maintain as a monolithic spec.

Today, we highlight the progress of #CSS specifications in #FirstWorkingDraft status on 3 levels: 3, 5 and 6! #timetogiveinput

This CSS module solves 3 main use-cases: 1) coloring scrollbars to blend into the UI of a #WebApp, 2) thinner scrollbars on small elements and 3) hiding scrollbars while still allowing other ways to scroll.
