Site layout

Cascading style sheets

Cascading style sheets (CSS) are used in this site to separate content from the display. The CSS contains positioning, layout, font, colours and style information for the entire web site.

Separating style from content makes life very easy for visitors who prefer to view only the content of a web page, or to modify the content. These could be blind or partially sighted people who might use a screen reader to interpret a page.

CSS also reduces the size of the HTML files. The CSS file is downloaded just once by the visitor’s browser and re-used for different pages on a web site. This reduces the bandwidth requirements for your server and also ensures a faster download for your visitors.


Tables have only been used to display data and layout forms. All data tables and forms contain additional markup that may help assistive technologies such as screen readers.


Using access keys there is a logical tab order through the forms. Information has been grouped where natural and appropriate.

HTML Language

Appropriate use of HTML 5 tags have been used throughout this site.


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 on this site include descriptive attributes. Purely decorative graphics include empty alt attributes.

Text contrast

We have checked the site’s font and background colour combination against the different colour blindness conditions and ensured that all information is still clear.

Adjusting text size

User can change the text size using the browser. In Internet Explorer this is done by going to the top menu and selecting ‘View’, then ‘Text Size’. Medium is the usual setting, so selecting Larger or Largest will increase the text size. Similar facilities exist in other browsers, normally on the ‘View’ menu. Your browser’s ‘Help’ menu should give you further information about making these adjustments.

Browser Support

We have made every effort to make this site usable for as many different web browsers as possible. Unfortunately, older browsers are not able to take advantage of current technology, and so the site does not look as ‘designed’ as it does in modern browsers, although all the information should be accessible. We would encourage all users, if at all possible, to update their browser to the latest version – not only for this site, but to enhance your use of the web in general. Latest versions of commonly used browsers may be downloaded from:
