Hi Ashley, Thanks for the feedback. However, I respectfully disagree about JAWS. There was a time many years and versions ago when screen readers didn't support id attributes as targets, but that's no longer true. I just tested my site with JAWS 14 in both IE9 and Firefox 17. In both browsers JAWS identifies the link as "Same page link Skip to main content", then if I click on that link using the left mouse button I jump directly to the "main region", and a couple of down arrows later I'm on the main heading. I actually wrote an earlier blog post about this very topic.
The guidelines are broken down by four main principles: perceivable, operable, understandable, and robust. Under each principle, there are guidelines that provide specific goals a website should work toward. Under each guideline, there are testable success criteria. Those criteria are graded A, AA, or AAA. This grade shows the level of conformity to accessibility, AAA being the highest. The law only requires A and AA guidelines to be met.
