This website complies with priority 1 guidelines of the W3C Web Content Accessibility Guidelines and the U.S. Federal Government Section 508 Guidelines. Pages are built on valid XHTML 1.0 Strict for structure and CSS for presentation, and use structured, semantic markup.
For example, H2 tags are used for titles. In particular, this enables JAWS users to skip to the next post using ALT+INSERT+2.
A modern web browser like Firefox, Safari or Opera is needed to make the most out of this site, but thanks to the separation of content and presentation it should be accessible to any browsing device, including Internet Explorer, even in its earlier incarnations.
Accesskeys
Most browsers support jumping to specific links by typing keys defined on the web site. This is a potentially very useful feature for many users. However, accesskeys often conflict with keyboard shortcuts defined by the browser or operating system. Because of this, this website does not use accesskeys.
Navigation aids
All tables have properly scoped header cells, to allow screen readers to render them intelligently. Where required, tables also have a caption and a summary.
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).
Whenever 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. To aid this, link text is never duplicated; two links with the same link text always point to the same address.
There are no javascript: pseudo-links. All links can be followed in any browser, even if scripting is turned off. There are no links that open new windows without warning.
Visual design
This site uses cascading style sheets for visual layout. If your browser or browsing device does not support stylesheets at all, the content of each page is still readable. The site works surprisingly well as an AvantGo channel (for PDAs) with no extra work or pre-processing.
The layout is completely liquid, simply filling its viewport (window). It happily accommodates resizing text and, as relative units have been used, text can even be re-sized in Internet Explorer for Windows.
