This a great handy and practical little but big book. It helped a lot with my HTML/CSS pages it is a really awesome book. I would recommend this to anyone that is in a Computer field.
Quick, convenient alphabetical reference to HTML5 syntax right at my fingertips. I still find dead-tree books quicker to navigate than websites or Kindles (sorry Amazon) for this type of information. Each entry is tagged as to whether it is "not in HTML 4.01", HTML5 only, W3C or WHATWG. The appendixes list the common character entries and give an XHTML syntax overview. The front matter contains a concise list of HTML5 event handlers (ondrop, ondrag, etc.), and an excellent list of all the HTML5 elements organized by function appears just after the last alphabetic element entry. Another superb O'Reilly Pocket Reference.
