Standards compliance

The Word Wide Web Consortium (W3C) is an organisation that employs experts who know how to make websites more accessible or easier to use. The W3C experts have written a number of standards or guides to help website developers ensure that the sites they are building are accessible to as many people as possible. The pages on this website have been built to target the AA standard.


We aim to include descriptive ALT attributes for all content images used on this site. Graphics of a purely decorative nature include null ALT attributes.

Text Size

You can view this site using the standard text size or you can choose to make the text larger (or smaller) by changing the text size option in your web browser. Just click on the AAA link in the top menu of the website.
