Cascading style sheets (CSS)
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.

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 color combination against the different colour blindness conditions and ensured that all information is still clear.
Adjusting text size
This website is built using relative font sizes, which means that you can choose if you want to see larger or smaller text 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.
