The site uses a stylesheet and relative font sizes on all text with the exception of graphical text. The font size of text can be increased or decreased in size by using the “view” option in the browser.

All images, where appropriate, have an alternative text attribute. This means that when an image is conveying important information its content is described with an alternative text. Where an image is used for a decorative purpose the alternative text attribute will be left blank.

No information is exclusively conveyed using colour.

Our pages are designed so that they are without horizontal scrollbars when they are viewed at a screen resolution of 1024 x 768 pixels or higher.

A site map exists to provide information about the layout of the website.
