An overview of the development of CSS3 (Cascading Style Sheets version number three), which is a language for the presentation layer of web design and development. While this book covers the what of CSS3, and much of the why, the book doesn't contain explanations of how. So while someone looking for some quick tips, code examples, or tutorials won't find them here, I recommend this book for anyone who wants to know about the development of the markup language from a conceptual and overall design perspective.
Some of the best information I found was which modules are in what stages of development, and which modules aren't really being developed. The modules in the final stages of development are generally widely compatible with most web browsers, and the modules that aren't yet there may be available with browser specific code entries. Of course, some modules are in the very early stages, and although these may not ever be used, it's interesting to think about where style sheets may be in the future.
While this information is presented with design and engineering in mind, the reality is that millions of web sites will likely use new features. Thus, there is valuable business information for both businesses looking to improve in the future, and for technical people looking to stay up to date with cutting edge and wide scale changes.
This free e-book is a very high-level discussion of ongoing changes to the CSS3 modules. General information is given for each module, but specific CSS properties are not listed. If you want an executive overview of CSS enhancements and deprecations in some 30 pages, this book is helpful. However, this book lacks the details needed by a developer.
Decent book, but of course at the time of reading, it was slightly outdated since a lot of the features are now supported in browsers without prefixes. Not only did it talk about what is new in CSS3 but it talked about somethings that were in 2.0, removed in 2.1, always existed since 1.0 but ignored and somethings that will be in 4.0.
