Web Accessibility is so important. I have a friend who is visually-impaired and of course, since he has never seen what a Web page looks like, it is so hard to explain to him what is on a Web page, the layout, navigation, etc. It really opens up my eyes to the barriers on the Web for the disabled after sitting with him for an afternoon trying to help him get around on the Web.
There aren’t many free tools out there to help with checking for Web site accessibility. Bobby used to be free, but was taken over by IBM last year and is no longer offered for free. I have since come across a great tool to check your Web site for accessibility. It is called WAVE. It was created by the WebAIM organization.
WAVE is available as an add-on to Firefox so that it is readily available in your toolbar at all times. You can also go to the WAVE site and enter a URL and ask it to “WAVE this page”! It will evaluate the page for you and tell you if there are any accessibility errors on that page. It does not evaluate the whole site, just that page. You have the options to upload a file and copy/paste HTML code to be evaluated. You can also provide a link on your Web page to the WAVE report for your page.
Although this tool is in Beta it is worth checking out.
