Website access

The design of our website includes a number of accessibility features including:

  • The ability to adjust text sizes
  • Alternative texts for images
  • The use of cascading style sheets

Increasing text size

On every page there is a shortcut to increase the text size (see the three As on the top left of the screen), or alternatively select ‘text only’ to remove all images from the site.

You can change the text size by using your Internet browser menu (NB the default size for most browsers is "medium" or " 100%").


Alternative texts for images

If you hover the cursor over an image on this website, you will see a text description.

This is to provide further detail about an image, enhance access, and to provide information if you are surfing the web with the graphics turned off, or with text-only browsers.


The use of Cascading Style Sheets (CSS)

CSS allows a website to display information in a number of different ways, enhancing the accessibility of the content. 

It allows content to be displayed for different reading methods, such as on-screen, in print, by voice (when read out by a speech-based browser or screen reader) and on Braille-based, tactile devices.

This website provides the following style sheets:

  • Style sheet for standard web browsers
  • A text-only style sheet, which is easier to view on small screens e.g. PDAs & mobile phones
