Hi all, just a small bit of feedback, just to confirm:

The CSSWG defined CSS3 as "everything after CSS2"

To make it perfectly on point, should that be CSS2.1 ?
Based on this link

It’s been helpful for people to call CSS3, CSS4, and CSS5 as "eras,"

Just wondering if we should still mention the word era, I like it, but I know some had the feedback of an era being more a historical term. as an era is "a period of time beginning with some special date or event".
But this could become a special date of course

Agree with @brechtDR 's concern on era. But other than that this looks perfect IMO.
