About this page

This page outlines some of the accessibility features of the site, and guidance on how to use them. Please refer to your web browser and operating system 'Help' for their additional accessibility features.

Standards compliance

We aim for the site to comply with priority level 1 of the Web Accessibility Initiative (WAI) guidelines, part of the World Wide Web Consortium (W3C).

All pages on this site validate as XHTML 1.0 and use structured semantic markup.


The site has been optimized to be viewed at a minimum screen resolution of 800 x 600 within the following browsers or, their corresponding higher version numbers:

  • Internet Explorer 6
  • Netscape Communicator 7.2
  • Firefox 1.0
  • Opera 8.0
  • Safari 2.0

The pages do not use tables for design or mark-up purposes, and are not based on frames.

They can therefore easily be printed by clicking on the 'Printable version' button within every page of the website.
Text is set to relative sizes. This means it can be increased or decreased for more comfortable screen reading.


This primary navigation is supported by the top bar navigation which allows users to access the main content pages.
Subsidiary navigation, to obtain detailed information about research, is provided in the left-hand navigation bar.
Where links to subsidiary pages take the user away from main content pages, these links will open in a new window.
All navigation items use text, rather than graphic images, for improved readability.

Navigation has been designed to be as user-friendly as possible, allowing all site content to be viewed within the minimum number of mouse clicks.


Any informational image is provided with relevant alternative text.


The site has been designed using text-based CSS (Cascading Style Sheets), an approach which separates the structural content of the site from the design elements, thus enabling those using screen readers and other devices to access the content in the logical order it is written.

No tables or frames of any kind have been used in the design of this website.

Printing pages

All pages on this site are optimised for printing. Navigation bars and headers do not print and the content is arranged in a print-friendly manner under its logical headings.

To see what will print, click "File" and then "print preview" on your browser's menu bar.
