Accessibility features

The information on our website should be easy to access for everyone. To this end we have tried to make the site as “user-friendly” as possible and made every effort to make it navigable for users with a visual impairment.

We have tried to make the site simple to use with features including:

  • Full site search, covering the contents of every page
  • A sitemap, showing all the pages in each category
  • Clear and consistent navigation, with main categories available on every page

We have also made sure that the website complies with all relevant standards so that information is available to those using non-standard browsers and assistive technologies such as text-to-speech software. We have been particularly careful to ensure that the text size across the whole of the site can be adjusted to help those with low vision.

Because we use the newest technologies, users with a visual impairment don’t have to use a downgraded, “text-only” version of the site. The cost of using new technology is that the design does not look at its best in older browsers.

Please note: We open external links in new windows by default. We believe this is a useful feature, but we are aware that some accessibility guidelines advise against it. If you find this frustrating, or any other aspect of the site, please let us know.

Varying text size

The text size across the whole of the website can be adjusted to ensure that it is easily read by those with low vision. The procedure for doing so differs from one browser to the next. The instructions below outline the procedure for some popular browsers. If your browser does not appear here, in general you will get somewhere by following these guidelines: looking under the “View” selection on the main menu, you should find an option called “Text Zoom” or “Text Magnification” or “Text Size” or “Font Size”. From there it should be relatively simple to find and select an additional submenu option that adjusts the text size to your needs.

Browser-specific instructions

If using Internet Explorer

  1. Click on ‘View’ at the top of this window. ‘View’ will be between ‘Edit’ and ‘Favourites’, directly below the title bar.
  2. A drop-down menu will appear. One of the options will be ‘vary text size’. Select this option.
  3. A list of different text sizes will appear to the right of the mouse. ‘Medium’ is the default size for text. By selecting other values, you can enlarge or reduce the text as you require.
  4. Once you have selected a size, the page will automatically be redrawn using the new sizing.

If using Netscape Navigator or Mozilla

  1. Click on ‘View’ at the top of this window. ‘View’ will be between ‘Edit’ and ‘Go’, directly below the title bar.
  2. A drop-down menu will appear. There are two options: ‘increase font’, and ‘decrease font’.
  3. Once you have selected an option, the page will automatically be redrawn using the new sizing.

Alternatively, you can press ‘CTRL + +’ to increase the size, and ‘CTRL + -’ to decrease it.

Standards

This site is Double-A compliant to WAI and Bobby guidelines, as recommended by the Royal National Institute of the Blind (UK). Conformance to these guidelines help make the Web more accessible to users with disabilities and benefit all users.

There are too many accessibililty features to list here, but some of the more interesting or relevant features include:

  • Pages are organized to be fully functional, even with javascript turned off
  • All text uses relative font sizes so text can be enlarged or reduced using the text size options available in visual browsers (see instructions below)
  • All pages use flexible page formats so pages can be automatically resized for different window sizes and screen resolutions
  • All pages are designed with separate cascading style sheets, so they can be replaced by user-defined style sheets
  • Changes in function of differents parts of a page (e.g. navigation, content) are clearly labelled when using adaptive technology
  • Changes in language are labelled clearly
  • Use of extra metadata generates standardised navigation in supported browsers (Lynx, iCab, Mozilla, Firebird and Opera)
