Web designers and developers alike are increasingly enthused about the capabilities offered by HTML5, which is generally considered the combination of the latest version of the Web's primary markup language and its related technologies. Consequently, publishers have rushed to market a wide variety of books that purport to explore the inner mysteries of HTML5, even as the standards — and how browsers implement them — are still in flux. In characteristic fashion, O'Reilly Media took the time to wait for some of the dust to settle, and attempted to create a resource more approachable and solid than those thrown together quickly. The final result is Head First HTML5 Programming.
The release of this book is quite timely, given the current developments in web technologies. As one of the underpinning components, HyperText Markup Language (HTML) has undergone tremendous change during its two-decade history — with new element names and attributes being added to try to keep up with the latest multimedia formats, design techniques, and other factors in the Internet's evolution. Even though this newest major revision, HTML5, is still not completely supported by most browsers, much of its capabilities are already available, to one extent or another. Also, forward-thinking designers and developers are not waiting for the final blessing by the W3C to begin learning what they can do with it now and in the future.
This book was written by Eric Freeman and Elisabeth Robson, both of whom possess a lot of experience with the subject matter. This title was released on 18 October 2011, under the ISBN 978-1449390549. Its considerable size, 608 pages, is partly due to the extensive use of humorous pictures, actors, scenarios, clever drawings, and a generous use of whitespace — characteristic of other titles in the Head First series. At first glance, these elements might seem like cartoonish gimmicks, meant only to boost the page count or keep graphics employees busy. Actually, these methods are intended to help readers retain the new knowledge, and make the learning process more pleasant. This approach is covered in more detail in the book's introduction.
The example code is generally of good quality, but not always consistent; for instance, is employed in some places, but elsewhere — leaving the reader to wonder why. Also, there's at least one case of (incorrect) curly quotes in the code (page 454). It is helpful to have the example code available for download, although it would have been decidedly better had the root directory of the archive file contain an index.html pointing to all of the included apps, so readers could bookmark that single starting point, rather than having to modify their browser's URL each time. In addition, it is oftentimes not obvious as to which chapter subdirectory corresponds to any given location in the book.
However, the main problem with this book is the sloppy editing, evidenced by the notably high number of errata: "pin point" (page xiv), "test editor" (xxii; should read "text editor"), "iPhone" (xxv; should read "HTML5" or something similar), "folks that" (xxxi; should read "folks who"), "get [a] sense" (1), "on the page 2" (3), "can you get a long way" (21), "assign it [the] empty" (26), "you can also thrown in" (40), "its got" (46), "Your job is the act like" (57), "lets concentrate" (58), "get [the] length" (68), "Go ahead an open up" (90), "What you can" (129; should read "What can you"), "a object" (142), "an new object" (147), "to to" (158), "you [are] saying" (158), "users location" (166), "sourth" (167), "three properties" (177; should read "four properties"), "google" (186), "including [the] last two methods" (192), "give it a try it" (218), "will use" (220; should read "we'll use"), "take a 90 milliseconds" (221), "the this code" (249), "with out with" (268), "HTML =" (271; should read "HTML5 ="), and "an drawable region" (285). These are just the errata found in the first half of the book. Fortunately, they are in the narrative, and not the example code, which would have had a much more negative impact upon the reader.
This book is definitely an introductory tutorial, and by no means a reference. Not all of the new HTML5 elements are covered, nor is CSS3 provided full coverage. The repetition of concepts may aggravate experienced or impatient programmers: For people with some experience with these technologies, and for people who readily glean information from technical books upon first exposure to the given concept, the frequent repetition in this book would border on tiresome, if it weren't presented so pleasantly, oftentimes with humor. On the other hand, the Head First books are predicated on the approach of presenting information in different formats, to maximize learning. Any newbie should appreciate this volume's clear explanations, even if they are presented multiple times, but differently. Also, there is plenty of testing of one's knowledge, to reinforce what has been learned.
