We’re committed to making this website accessible and usable, and will continue to make efforts to improve where we can.

Images

All content images used in this site should include descriptive alt tags. Purely decorative graphics include null alt tags.

Complex images include longdesc tags or inline descriptions to explain the significance of each image to non-visual readers.

Downloadable files

Our publications are available to download from this website in Adobe® PDF file format. Other documents are available in a variety of formats including PDF, Microsoft Word (MS Word) and Microsoft Excel (MS Excel). Most computers already have software to open these document formats, but free document readers are also available to download:

Newer versions of Adobe Acrobat Reader (6 and above) have incorporated accessibility features which can be accessed in the Edit preferences menu.

If you can’t use Acrobat Reader to access these documents, Adobe provide a free online conversion tool which will covert PDF documents into web pages (HTML) or plain text.

Visual design

This site primarily uses cascading style sheets for visual layout. The use of tables for layout has been kept to a bare minimum.

This site uses only relative font sizes, compatible with the user-specified “text size” option in visual browsers.

If your browser or browsing device does not support style sheets at all, the content of each page should still be readable.
