A literal lifetime ago, or more for at least some of our readers, I in the very early days of CSS developed a CSS editor called Style Master.
Back then, browser support for CSS was to be generous, very patchy. One of the really significant challenges for designers and developers was navigating the inconsistencies between Netscape Navigator 4 and Internet Explorer versions 3 and 4 and then 5 for CSS.

We went and tested every feature of CSS in every major browser, and built a very, very early compatibility table for these browsers and their CSS support.

It wasn’t the very first that honour belongs to Eric Meyer, still going strong in the web and CSS world. Since then, of course, we’ve seen many projects that do something similar, in particular, Can I Use which is now widely used by the likes of MDN and elsewhere.

But this is a fantastic breakdown of all the properties in CSS by when they were introduced. And it includes links to the specification and to Can I Use for details on support.
