Standards Compliance

  1. Where possible, all pages on this site are WCAG AAA approved, complying with all priority 1 and many priority 2 guidelines of the W3C Web Content Accessibility Guidelines.
  2. Where possible, all pages on this site are Section 508 approved, complying with all of the U.S. Federal Government Section 508 Guidelines.
  3. Where possible, all pages on this site validate as XHTML 1.0 Transitional.
  4. Where possible, all pages on this site use structured semantic markup. H2 tags are used for main titles, H3 tags for subtitles. For example, on this page, JAWS users can skip to the next section within the accessibility statement by pressing ALT+INSERT+3.

Links

  1. Many links have title attributes, which describe the link in greater detail, unless the text of the link already fully describes the target.
  2. Wherever possible, links are written to make sense out of context. Many browsers (such as JAWS, Home Page Reader, Lynx, and Opera) can extract the list of links on a page and allow the user to browse the list separately from the page.
  3. Link text is never duplicated on the same page; two links with the same link text always point to the same address.
  4. Outside of minor exceptions, there are no "javascript:" pseudo-links. Links can be followed in any browser, even if scripting is turned off.
  5. The following images and link text are used to designate that links open new windows:
    1. New window icon
    2. photo
    3. "Learn more... > >"
    4. "Submit..." or "Report..."
    Other than minor logical exceptions, there are no links that open new windows without warning.

Images

  1. All content images used in this site include descriptive ALT attributes. Purely decorative graphics include null ALT attributes.
  2. Complex images include LONGDESC attributes or inline descriptions to explain the significance of each image to non-visual readers.

Visual Design

  1. This site uses cascading style sheets for visual layout.
  2. This site uses relative font sizes, compatible with the user-specified "text size" option in visual browsers.
  3. If your browser or browsing device does not support style sheets at all, the content of each page is still readable.
