Accessibility

STANDARDS COMPLIANCE

  • All pages on this site are WCAG AA approved, complying with all priority 1 and 2 guidelines of the W3C Web Content Accessibility Guidelines. Again, this is a judgement call; many guidelines are intentionally vague and cannot be tested automatically. This site has been reviewed and it is believed that all these pages are in compliance.
  • All pages on this site validate as HTML5 1.0 Strict. This is not a judgement call; a program can determine with 100% accuracy whether a page is valid HTML. For example, check the home page for HTML validity.

TEXT

  • This site uses only relative font sizes, compatible with the user-specified "text size" option in visual browsers. For those using Internet Explorer, go to View > Text Size > and select your desired size. For Firefox users, simply hold the CTRL button and press + or - to increase or decrease the size.
  • 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.

VISUAL DESIGN

  • This site uses cascading style sheets for visual layout, and semantic HTML for structure.
  • If your browser or browsing device does not support stylesheets at all, the content of each page is still readable.
  • All images used in this site include descriptive ALT attributes. Purely decorative graphics include null ALT attributes.
