These first CSS Level 5 modules come at a time of very active discussions on the value of numbered "versions" of #CSS - e.g. @ppk recently wrote "CSS4 is here!" quirksmode.org/blog/archives…

It's an opp. to clarify the land of #CSS levels... Of all CSS levels, CSS Level 2 (or CSS2) is the last monolithic level of CSS published as a @w3c #WebStandard, May 1998 - note the vintage look!: w3.org/TR/1998/REC-CSS2-1998…

This specification was eventually renamed CSS 2.1 (a revision was published in June 2011 - Editors were Bert Bos, @viumlie, @Hixie and @t)

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.

That's why, starting from 1999, #CSS was decomposed into modules, each having its own life at its own pace. Each module defines a part of CSS to allow more immediate, incremental improvement of the specification: w3.org/Style/2011/CSS-proces…

The @csswg occasionally publishes a list of stable modules to tell #implementors the current state of CSS, that is the "CSS Snapshot": w3.org/TR/CSS/

It is important to note that the @csswg decided not to try to describe #CSS for users and #developers. The group works primarily for implementors and hopes others like MDN would create resources for devs. For ex., check the CSS reference on @MozDevNet: developer.mozilla.org/en-US/…

So, back to CSS4's marketing question: github.com/w3c/csswg-drafts/…
Last month, @chriscoyier wrote a CSS-Tricks an article simply titled "CSS4" where he reminds what was and is on people's minds: css-tricks.com/css4/

A @w3c CSS4 #CommunityGroup was recently launched to give more space for the discussion of what would a CSS4 label encompass - join if you want to help!

As always, all the #CSS documents from the @csswg are developed on their github repo: github.com/w3c/csswg-drafts
