This was a book that I had picked up to help me out with my college classes, and I went through it very thoroughly as I used it to aide in accomplishing assignments. Overall it was an ok quick overview of EVERYTHING to do with HTML5, but it didn't really have much of a focus on any one area and expound upon it much. There were a lot of great little tips though and I learned a few things from it, so I mark that as a win. A solid 3.5 stars for me.
