From advanced selectors to generated content to the triumphant return of web fonts, and from gradients, shadows, and rounded corners to full-blown animations, CSS3 is a universe of creative possibilities. No one can better guide you through these galaxies than world-renowned designer, author, and CSS superstar Dan Cederholm. Learn what works, how it works, and how to work around browsers where it doesn’t work.

I think you can see these games as pieces of a puzzle. You will need all the pieces to understand the big picture.
Also there a some books from A Book Apart you can try. https://abookapart.com/search?type=product&q=CSS
Maybe start with CSS3 for Web designers by Dan Cederholm https://abookapart.com/products/css3-for-web-designers

Instead I was greeted with this quote in the book:
The [JavaScript] APIs in HTML5 are very powerful. They are also completely over my
head. I’ll leave it to developers smarter than me to write about them. The APIs
deserve their own separate book.
Fair enough. Those are rather technical subjects and this is an introductory book. I can live with that.More than this being an introductory book, it's a book for designers. The target audience is neatly contained in the title of the book. This means that developers aren't going to get everything they might want out of this book. As he mentions in the article, the term "HTML5" has become an abbreviated moniker for a fairly large set of new-ish web technologies and standards. I'd expect a book entitled HTML5 for Web Designers to read more like CSS3 for Web Designers.
