How to change the appearance of this site

Where possible, we have created this site so that your own preferences for colours, fonts and text sizes will take precedence over ours. The following resources will help you modify your own browser and operating system preferences to suit your own need:

Text Size

If you need to change the text size of the content on this site and you are using Internet Explorer, go to the 'View' menu and select 'Text Size', and choose your preferred size from the list, you will not notice the change in text size on the page you are viewing and all pages across the site.

Text Colour

If you need to have different colours on all the web pages that you visit, you can set your browser to apply certain rules about colours and text sizes to all web pages you visit. In Internet Explorer, for example, select the 'Tools' menu - 'Internet options'. Now select the Colours and Fonts of your choice. Once you have done this, select the Accessibility button and check the boxes to ignore font sizes, styles and colours specified on web pages (it will then use your defaults instead).

Access Keys

An access key allows a website user to quickly jump to specific areas of the site by use of a keyboard. For more information go to

Use of access keys depend on your computer's operating system:


With Windows-based systems the user has to press the 'Alt' key and the access key (followed by pressing the 'Return' or 'Enter' key for MS Internet Explorer).


With the Macintosh system the user has to press the 'Ctrl' key and the access key.
