Accessibility
Standards compliance
Standards compliancees on my sites are Bobby AAA approved, complying with all the Bobby guidelines. This is always a judgement call; many accessibility features can be measured, but many can not.
I ensure all pages are WCAG AAA approved, complying with all priority 1, 2, and 3 guidelines of the W3C Web Content Accessibility Guidelines. Again, this is a judgement call; many guidelines are intentionally vague and can not be tested automatically.
All my pages use structured semantic markup. H1 tags are used for main titles, h2 tags for subtitles. For example, on this page, JAWS users can skip to the next section within the accessibility statement by pressing ALT+INSERT+2.
Navigation aids
All pages have relative home links to aid navigation in text-only browsers. Netscape 6 and Mozilla users can also take advantage of this feature by selecting the View menu, Show/Hide, Site Navigation Bar, Show Only As Needed (or Show Always).
Links
Many links have title attributes which describe the link in greater detail, unless the text of the link already fully describes the target (such as the headline of an article).
Links are written to make sense out of context.
Images
All content images used include descriptive ALT attributes. Purely decorative graphics include null ALT attributes
Complex images include LONGDESC attributes or inline descriptions to explain the significance of each image to non-visual readers.
Visual aids
I always use cascading style sheets for visual layout.
This site uses only relative font sizes, compatible with the user-specified "text size" option in visual browsers
If your browser or browsing device does not support stylesheets at all, the content of each page is still readable.
JavaScript
An alternative is provided for non JavaScript supporting browsers.
