Want to determine whether your web site (or a web site you are visiting!) follows general accessibility guidelines? While it is crucial to test a site with actual users to ensure that your content is universally accessible, there are a number of standardized guidelines that you can follow to make a web site more accessible to everyone who uses the Web, and there are a number of tools that can help.
To learn more about accessible/universal web design, check out the
Web Accessibility Initiative. They have also developed a
