Accessibility

If you have any questions or comments about the accessibility of this site, feel free to contact us.

Standards compliance

1. All pages are Bobby AA approved, complying with all priority 1 & 2 guidelines of the W3 Web Content Accessibility Guidelines.
2. All pages validate as XHTML 1.0 Transitional.
3. All pages use structured semantic markup. For example, H1 tags are used for
4. page titles, H2 tags for sub-titles and the navigation is structured in a list (UL tag).

Navigation aids

1. All pages on this site include a consistent set of global navigation links.
2. All pages on this site include a search box.

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. 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; 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.

Images

1. All content images used on this site include descriptive ALT attributes. Purely decorative graphics include empty ALT attributes.

Visual design

This site and all its archives use cascading style sheets for visual layout.

1. Text can be resized using the options in your web brower (View » Text Size in Internet Explorer and Firefox).
2. If your browser or browsing device does not support stylesheets at all, the content of each page is still readable.
