Accessibility Information for this Website

If you have any questions or comments about the accessibility of this site, please contact the webmaster.

Standards Compliance

  1. Pages conform to the W3C Web Content Accessibility Guidelines, both priority One and Two checkpoints where possible on the site.
  2. All pages on this site have been designed to comply with section 508 guidelines.
  3. All pages use structured semantic markup.
  4. Where possible all pages validate as HTML transitional.

Access keys

Most browsers support jumping to specific links by typing keys defined on the web site. On Windows, you can press ALT + an access key; on Macintosh, you can press Control + an access key. All pages on this site define the following access keys:

  • Access key 0 - Accessibility Page
  • Access key 1 - Site Map

Navigation aids

  1. At the top of the page (beneath the banner) is a breadcrumb trail showing you exactly where you are in the hierarchy of the site.
  2. At the very top of the page is a link to a site map, showing the sections and categories of the site.

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 (such as the headline of an article).
  2. Whever 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; two links with the same link text always point to the same address.
  4. There are no "javascript:" pseudo-links. All links can be followed in any browser, even if scripting is turned off.
  5. There are no links that open new windows without warning.

Images

  1. All content images include descriptive ALT attributes. Purely decorative graphics include null ALT attributes.
  2. Full descriptions for graphs, diagrams, and other complex images are provided through a link immediately following the image.

Visual design

  • This site uses cascading style sheets for visual layout.
  • All decorative design images are served via CSS, and the entire layout scales with font resizing.
  • The content of each page is still readable if your browser or browsing device does not support stylesheets.
