Errata for Head First HTML5 Programming

"test editor" should be "text editor"

"But we assume that if you’re holding this book, you really want to learn about iPhone development." Not sure, but I think this text was copied and pasted from a book on iPhone development. This book might (haven't looked ahead) contain some information about mobile development with HTML5, but that's not its primary purpose!

Note from the Author or Editor:
Change to "you really want to learn about HTML5 and JavaScript."

The picture's label says "Rebeca Dunn-Kahn". The sentence at the bottom that lists the team members says "Rebeca Dunn-Krahn".

through Webville to get sense for everything that goes into “HTML5.” The above text should probably be through Webville to get a sense for everything that goes into “HTML5.” IMHO, "for" should be replaced by "of". Also, the line that begins with "HTML5" is slightly outdented for no reason (a PDF generation error?).

Note from the Author or Editor:
Change "get sense for" to "get a sense of". Outdenting is correct; that's the way lines that start with quotation marks are supposed to look.

"In fact, what everyone is excited about is the ability to build rich, interactive pages (or even sophisticated web applications), and to support that HTML5 provides a whole family of technologies that works hand in hand with the HTML5 markup language." The above doesn't appear to be a sentence. It should probably be something like In fact, what everyone is excited about is the ability to build rich, interactive pages (or even sophisticated web applications), and to support a whole family of technologies that works hand in hand with the HTML5 markup language. or In fact, what everyone is excited about is the ability to build rich, interactive pages (or even sophisticated web applications), and the support that HTML5 provides for a whole family of technologies that works hand in hand with the HTML5 markup language.

Note from the Author or Editor:
I added a comma that I hope will clear things up, so it reads: "In fact, what everyone is excited about is the ability to build rich, interactive pages (or even sophisticated web applications), and to support that, HTML5 provides a whole family of technologies that works hand in hand with the HTML5 markup language."
