Navigation
Access keys
Current thinking suggests that access keys have limited browser support and may interfere with assistive technology and screen readers. Therefore we have decided not to use access keys on this site.
‘Skip navigation’ link
At the top of our pages is a hidden link that can be spoken by screen-reading software. When selected, reading will skip the rest of the menu items and start at the beginning of the main page content.
Links
All links display titles, which you can see if you hold your mouse over the link. Adjacent links in text are surrounded by [square] brackets and spaces.
Scripts
There are no ‘javascript pseudo-links’. All links can be followed in any browser, even if scripting is turned off.
Text size
You can easily make the text on this site larger or smaller using your browser:
Internet Explorer & Firefox
- Click on the ‘View’ menu in your browser
- Click on the ‘Text size’ option
- Select the size you would like to see
Firefox alternative
Press the Control key and the plus sign on the numeric keypad to increase text size, and Control and numeric keypad "0" (zero) to return to the default text size. To make the text smaller, press Control and the minus sign on the numberic keypad.
Visual design
This site uses cascading style sheets for visual styles. If your web browser does not support stylesheets, the content of each page is still readable.
Images
All content images used in this site include descriptive ALT attributes. Graphics intended purely for decoration have null ALT attributes.
Text only version
As this site uses CSS and semantic XHTML for markup, it is not necessary to have a separate text-only site; visitors with graphical and non-graphical browsers see the same information.
PDF Files
We have used the PDF format for documents that are intended for download. This format allows documents to be read on a variety of computer systems. Adobe Reader is a PDF reader that is freely available for several types of computer systems.
