Overall, I can say that I was relieved that I really enjoyed the book, and can see myself using it regularly to reference a number of HTML5-related topics - especially some of those that I wasn’t already familiar with. He responded to my email the same day, and the book arrived shortly thereafter. So I was pretty excited when Mark Pilgrim sent out a tweet offering free review copies of his new HTML5 book HTML5: Up and Running, courtesy of O’Reilly Media. While a number of titles have been incorporating CSS3 into their content since before 2010, this year has seen major book releases that are focused primarily on HTML5. As far as web design literature goes, I think it’s safe to say that 2010 has been the year of HTML5 books.
