Abstract:

Let’s take a look at 10 ways to improve the accessibility of your XHTML website by making it standards-compliant. We’ll go the extra mile and include criteria that fall beyond the standards set by the W3C but which you should follow to make your website more accessible. Each section lists the criteria you need to meet, explains why you need to meet them and gives examples of what you should and shouldn’t do.
