Accessibility features


Text resizing
The website makes use of relative text sizes, allowing text to be resized within the browser, a feature supported by all modern visual web browsers. The site layout has also been constructed and styled in a manner designed to facilitate text resizing without presenting obstacles to accessibility.


Valid XHTML mark-up
The website conforms to W3C XHTML 1.0 Transitional mark-up to ensure that the content of the site can be accessed across as wide a range of technologies as possible. Best practice in semantic mark-up is used to give meaningful context to non-standard browser technologies and assistive technologies.


Progressive enhancement
Cascading style sheets (CSS) and JavaScript are used throughout the website, to enhance both the visual appearance of the site and the user experience. Progressive enhancement techniques are employed so that the site is fully functional if either technology is disabled or is not supported.


Colour combinations
Where possible, the site uses text foreground/background colour combinations which produce a strong contrast, along with increased line-height and white-space, in order to increase the readability of content.


There are few images on this website or within documents and where possible images are not used to convey complex information. However, where images have been applied, the content of is described using alt tags to convey the meaning of the image to non-visual technologies.
