Headings and navigation menus:

HTML heading tags are used to convey document structure. H1 tags are used for main titles, H2 tags for subtitles etc. Navigation menus are marked up as HTML lists. This ensures that the number of links in the list is read out at the start and it can be skipped easily.


All images used in this site include descriptive alt tag attributes. Where an image has no use other than being decorative the alt tag is set to null to allow easy reading of the site by all users.

Style sheets:

This site uses cascading style sheets for all visual layout. If your browser or browsing device does not support style sheets at all, the use of structured semantic mark up ensures that the content of each page is still readable and clearly structured.


The use of JavaScript has been kept to an absolute minimum. Where it is used then all pages and process are still accessible should JavaScript be turned off.


All links have been written to make sense when taken out of context. Where appropriate, we have also added link title attributes to describe the link in greater detail.
