Thanks to the authors and the publisher for the book promotion.
The discussions in the forum for this book have been very detailed and interesting. I went and looked up some of the other Head First books related so this subject , such as HTML5 , and may have to acquire them to keep this book company on my bookshelf. The authors have video training classes like the one introduced in this video that I am going to consider taking.
I am happy to have won this book for my bookshelf!
