This site was developed entirely with XHTML 1.0 Strict and Cascading Style Sheets Specification 2. As a result almost all of the presenation and HTML code have been seperated. The site is completely Open Source and makes extensive use of PHP and Apache and is hosted on a cheap Linux server.
Why Linux and not OS/400? Simply for my own learning experience. I've already got a successful website running RPG CGI on the AS/400 and this gave me a chance to do something different. Also, using PHP allowed me to experiment with some very cool modular site architectures. Most pages and divs are self contained code blocks reused in a series of require statments. The combination of this and CSS makes site wide changes quick and painless.
To learn about these techniques and a slew of other cool stuff, follow the W3Schools and Glish links to your right under "Web Essentials".
As a result of these approaches, this site should work on just about any reasonably up to date browser. It has been tested in the following browsers:
