Standards of compliance

We make sure that navigation throughout the site works in a consistent way.

We use a standard web font to make it easy for all to read. In most cases, the size of the font can be adjusted according to the users needs, using standard browser and operating system options.

All images are given ‘alt text’ alternatives except those which are only decorative. The ‘alt text’ for these are left blank.

We never use colour as the only way to convey information.

Other navigation aids

The main navigation links allow users to reach subpages quicker in graphical browsers. The navigation is still entirely usable in text-only and non-javascript browsers.


Wherever possible, links are written to make sense out of context. All links can be followed in any browser, even if scripting is turned off. There are no links that open new windows without warning. Title tags are used to show links will open new windows and go to other sites. JAWS screenreader users can change their settings to make sure these can be read.


All relevant content images used include descriptive alternate text (alt) attributes. Some images contain no informational value as they are purely decorative. In these cases ‘alt text’ is used, or the image is presented as a background image.

Visual design

This site uses cascading style sheets for most of its visual layout. If your browser or browsing device does not support stylesheets at all, the content of each page is still readable. This site uses only relative font sizes, compatible with the user-specified text size option in visual browsers.

Access keys

Access keys have not been used. This is a deliberate omission as the benefits from their use is highly limited and they can cause problems due to conflict with other software using shortcuts.
