HTML: Quick Accessibility Testing

A recent project of mine required me to do a quick review of the accessibility level of a site. Nothing serious, just to show what was possible to test and where the site scored right now. I managed to assemble a small list of tools that I believe did a rather good job. This article is a list of those tools, and some tips on how to use them. It covers three areas: automatic, semi-automatic, and manual accessibility testing.
