Just got back from the eduWEB conference in Chicago where I presented about content accessibility standards for higher-ed websites. More on this (and a possible screencast) later, but a couple of issues consistently arose from this and some emails and communication from others on the Drupal 7 Accessibility Task Force that I'm just putting out there.
1. Headings - how many and when?
Basically, h1 - h6 tags can be used by many assistive technologies to help disabled users scan a page. Some screen readers can be commanded to "read only headings." From a semantic standpoint, they also help web content maintain context that would otherwise only be conveyed visually. Now generally, the rule of thumb is this: one h1 heading, which must be unique OR the name of the site (if this is the homepage or it's otherwise appropriate), with subheadings filled in by h2 headings. On rare occasions that there are sub-subheadings of content, h3 tags should be used but generally on one page, it's more common to see one big heading, a few smaller headings, and maybe one really small heading. Anyway, the question has come up recently, is this appropriate? In certain situations, a page will need the name of the site and a unique title for the page visible on the page. Do we smush everything into one line then? Or do we have two h1 headings? That's essentially like a book with two titles. Visually it can distract the user and from an accessibility standpoint, would certainly confuse screen readers etc.
