Site structure and contentNavigation:
Headings and navigation menus:
HTML heading tags are used to convey document structure. H1 tags are used for main titles, H2 tags for subtitles etc..
All images used in this site include descriptive alt tag attributes. Where an image has no use other than being decorative, the alt tag is set to null to allow easy reading of the site by all users.
We have taken care to ensure that the site's font and background colour combinations contrast significantly and are effective in ensuring information is still clear when viewed in different colour combinations.
If you wish to override the site's colours, you can do this by changing your browser settings to your own preference.
The font sizes we use on our site are not scalable. We have therefore provided an alternative stylesheet which can be activated by clicking the next link.
This site uses cascading style sheets for some elements of visual layout. If your browser or browsing device does not support stylesheets at all, or you have chosen to switch them off, we have endeavoured to ensure that the content of each page is still readable and clearly structured without stylesheets.
Tables: To allow screen readers to render them intelligently, where appropriate we have used the TH tag to mark the column headings of the table columns.
Tables used for layout use none of the above attributes to ensure that they are not confused with data tables.
Forms and fields:
All forms fields follow a logical tab sequence to ensure easy navigation.
Form fields also have "id" attributes to explicitly associate the form field with its appropriate label to allow for easy entry of data.
All links have been written to make sense when taken out of context. Where appropriate, we have also added link title attributes to describe the link in greater detail.
We have tried to ensure that the copy on our website is well laid out and easy to understand.
Wherever possible, we would recommend upgrading your browser to the latest version number to take full advantage of this site
