Is your website accessible?

Webaim (http://webaim.org) is a Utah State University based organization that is dedicated to creating an accessible online world for people with disabilities. They offer technical assistance, training, examples, advice, tips and articles, as well as a way to survey your own site to see how accessible it is. Here's an infographic they offer that not only explains some of the key design elements for accessibility, but also demonstrates them in practice.
