Some of the measures we have taken to ensure our site is accessible include:
- Our website uses relative font sizes to enable users to change the size of text on the page;
- We use alternative text for all images on our website;
- All our web pages use valid XHTML;
- We conduct regular validation checks to ensure the HTML code of our web pages is valid.
All images on this site are accompanied by a brief alternative text which where appropriate identifies an image or its function. This alternative text (alt-text) is generally only visible when the browser's automatic image loading feature is turned off.
All text links are written so that they make sense when read out of context.
Documents on this website are provided in a variety of formats. The most common are Adobe Acrobat PDF (PDF) and Microsoft Word (MS Word). Most computers already have the software to open these document formats.
Most PDF files on this site allow basic accessibility. Simple PDFs should not represent an accessibility problem. However, despite our best efforts some PDF files may still not be fully accessible, such as scanned and older PDF files and those containing complex statistics and data tables.
If you are having trouble reading a PDF document on this website, Adobe offers a free online tool for converting PDF documents to HTML or text. For more information about PDF accessibility see the Adobe website accessibility section. For more help with Acrobat files generally and a link to download Acrobat Reader see the site help page.
