Hi msmith2276, welcome to the forums,
From the article's page 1
This information is an excerpt from my recently released book, Build Your Own Web Site The Right Way Using HTML & CSS, 2nd edition.
If you go to that book's TOC page http://www.sitepoint.com/books/html2/toc.php you'll see some links, including the one to it's code archive http://www.sitepoint.com/books/html2/code.php
I don't know if they have your email stored yet, but if you ordered the book you should have access soon.
BTW, don't forget to check out the book's Corrections & Typos, it will save you some trouble.
