A reader of my HTML book, Omar, emailed today and pointed out an error in my "HTML, XHTML, and CSS: Your visual blueprint to designing effective web sites" book. On page 142, while I correctly describe the process for creating ID selectors in the main text, I have a note between steps 2 and 3 that says, "Note: Remember that ID names must begin with a period." Obviously, this is wrong: ID names must begin with a pound sign.

These books really are very carefully edited. Not only do I read over the text an almost nauseating number of times, but its also read by the project editor, the copy editor, and the tech editor. And yet even with all of those eyes looking at it, mistakes still slip though.

I've written to Wiley and asked that an errata section by added to the book's official web site. It's not that I necessarily expect more errors, but the reality is that they probably exist, and hey, even if there is but this one, it's still worth noting on the site.

So many thanks to Omar for bringing my attention to the error.
