Before I continue, let me say that this will mainly be a review of The Missing Manual format. Rather than spend many paragraphs talking about how amazing the content is, I'll cut to the chase:
This book will teach you CSS3, Good Practices, Why it's Useful, and how you can create Responsive websites with it. I didn't read very in-depth because I already know and use CSS3, however it's a great review book.
And now on to The Missing Manual.
This is a great book format. Many technical books are either too boring, too gimmicky, or they don't teach you well. The missing manual contains some classes Gimmicks, however they're scattered and formatted well. Some examples:
- "Notes". They were formatted to interrupt you on purpose. Rather than be tucked away, they help reinforce information while you're reading. They were very helpful.
- Sections separated smartly.
The black-on-white format of the missing manual is used to it's advantage, with simple graphics and a great layout.
If you want to learn everything about CSS3, this is a great place to start.
