Images on the site contain 'alt tags,' which aid users who listen to the content of the site by using a screen reader, rather than reading the site. Likewise, a 'skip to' link provides these users with a method for bypassing the main menu and going directly to the main content each time a page is accessed.
Relative font sizes are used, so that a user can enlarge the font size (e.g. by using CTRL+ to magnify the text).
The site contains a sitemap, indexing all the pages currently available, including sections on each page. The sitemap is generated dynamically, which ensures that it will be up-to-date at all times.
