Abstract:

There are a lot of tools available to check your Web content for accessibility. Some tools are Web-based (such as WAVE 3.0). Other tools are stand-alone software products that you install on your hard drive. One tool that you may have overlooked is the Opera Web browser. Opera is not an accessibility validator—it's a Web browser—but it can act like an accessibility validator if you know how to use it that way. In fact, it's one of the best available. This article explains why.
