Site Accessibility This site has been designed from the ground up using current standards for Web site design and incorporates techniques that render it accessible to as wide a range of people, technologies and devices as possible.
The baseline for accessibility that we use is derived from the W3C/WAI "Web Content Accessibility Guidelines" (WCAG for short) version 1.0. We also incorporate other techniques and best practice solutions derived from experience and other sources.
There are absolutely no tables used for layout purposes so you will not have to take this in to account if you are using a text only browser or screen reader.
Structural elements such as headings, paragraphs and lists are used correctly and so can be used effectively for navigation or skimming in screen readers.
For Some Visual Impairments
For people with certain kinds of visual impairments, there is a facility in the column on the left that allows you to change the colours used on this site as well as features that let you alter the text size. These features are currently experimental and we would be glad to hear from you if you have any feedback that would allow us to improve this functionality. If you do not have JavaScript enabled in your browser, you will not be able to alter the text size this way but you will still be able to use the text size features offered by your browser in the normal way.
For Non-visual Users
For non-visual users, every page within this site has the navigation block placed at the start of the page. The very first element on each page is a link that will allow you to skip to the main content area.
For Keyboard Only Users
If you are using a keyboard only, each page is arranged sufficiently to allow you to tab through in a logical order. Navigation comes first followed by content. There are some hidden links for non-visual users, so you will have to tab four times to hit the first visible link on each page.
