Our Accessiblity Features
Accesskeys are keyboard shortcuts that are “programmed” into a site. They are activated by pressing a control key (usually ALT on a PC or Command on Mac) along with a particular letter or number. While accesskeys are a good idea in theory, they can actually interfere with normal browser shortcuts, so are used sparingly.
At this site, a few numeric keys have been implemented, following the (more or less) standard key assignments originally set by the UK government.
No particular font size has been at this site for normal paragraph text. That means that what you are now seeing is your browser default text size. If you aren't happy with the way it looks, you are free to change it to your liking. See how to adjust the text display in your browser.
The layout and all styling at this site is done using Cascading Stylesheets (CSS). All pages adjust to your particular window size, and the text is readable in virtually any browsing environment, though the layout may look a little different in different browsers or different display devices.
In addition, each page uses a “CSS Signature” (
<body id="www-c-net-us">), which facilitates applying a user stylesheet specific to this site.
Links and Images
Link text is intended to make sense out of context. Image alternative text is intended as a suitable replacement for that image; sometimes blanks are the best choice. Titles are used as needed on both links and images to provide more detail.
“Skip” links are special page navigation aids that allow keyboard users to more quickly get to particular parts of a page. The graphic design has them invisible by default, but they may be revealed if your browser supports tabbing through links, or if you are viewing the site with something other than a graphical desktop browser.
Two skip links are at the top of each page: one goes directly to the navigation menu and the other goes to the beginning of the content area.
This site uses semantic, structual markup and passes code validity checks. That means that we take great care to make proper use of headings, paragraphs, lists and other typography. Many browsers use structural markup as page navigational aids.
All pages have been examined for conformance to published accessibility guidelines.
Most, if not all, of the accessibility features at this site are used in other sites we develop.
