We have taken care to ensure that the site's font and background colour combinations contrast significantly to ensure information is clear.

If you wish to override the site's colours, you can do this either by using the buttons above or by changing your browser settings to your own preference.

Font size

The font used on our site are can be changed in size. You can do this either by using the buttons at the top of the page or by changing your browser settings to your own preference.

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.


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


All data tables have header cells, to allow screen readers to render them intelligently. Table summaries are used.

We have avoided using tables for layout purposes.

Forms and fields

All forms fields follow a logical tab sequence to ensure easy navigation.

Form fields have 'label' and 'id' attributes to explicitly associate the form field with its label to allow for easy entry of data.


Links throughout the site have been written to make sense when taken out of context.
