As usual with pages I've made, everything this site is written in XHTML 1.0 strict, except for the test results one, where I needed XHLML 1.0 transitional to allow for some of the features in the cut and paste html fragment presented, and most of the pages validates as such on the W3C HTML Validation Service (All of them when I latest checked them, but as I make some small changes I sometimes add some typo here and there that gets corrected later).
This site uses CSS for style informations, valid when I lates checked it (see above).
I've also checked the site for accessibility with Bobby and most of the pages were both Web Content Accessibility Guidelines 1.0 AAA (from the Web Access Initiative) and U.S. Section 508 Guidelines approved (again: when I latest checked them they were all approved, except the test results page, but I don't always check every minor change and I could always add some typo).
This page has been partially made with VIM 5.8 and Slackware Linux 8.0, and partially with VIM 6.2 under MacOS X; graphics have been created and/or edited with Image Magick 5.3.5 and 5.5.1 and TheGIMP versions 1. and 2.0.1, under both platforms. For the browsers I've used to test the page while I was developing, you can see the browsing suggestions section.
