|Introducing HTML 5|
Author: Bruce Lawson & Remy Sharp
It starts off with a look at the new tags and manages to convey the idea that the new tags are all about introducing semantics into your layout. No more is HTML a layout oriented markup system - it simply conveys meaning. For example, the <nav> tag indicates a chunk of HTML that provides page navigation e.g. a menu. What an item looks like is governed by the CSS. This is not a new principle but it is pursued more aggressively in HTML5. The book does a good job in explaining the new tags, showing how to use them and discussing what to do for browsers that don't support them.
Chapter 3 moves on to issues of more interest to programmers - forms and how to use the new form tags and facilities. Chapter 4 covers video and audio and bemoans the fact that the situation with codecs is so messy as to require multiple encodings of any video file you want to serve. Chapter 5 deals with Canvas and graphics in general. Chapter 6 is about data storage and the new facilities we have to store session and domain data. Finally the book rounds off with a look at offline options, the not-so-good drag-and-drop API, the easy to use Geolocation facilities and threading. The range of the book indicates what a mixed bag of technologies HTML5 is.
The authors discuss the pros and cons of HTML5 in an informal style. This certainly isn't a reference manual. It also doesn't provide real world example, there is a lot of detail missing. It also doesn't really discuss the impact that HTML5 will have on other technologies such as Silverlight and Flash - but then you probably need a crystal ball for that.
A good, straightforward but not deep introduction to HTML5.
Recommended if you want an overview with opinions, history and reasons why.
