We are fully committed to making the content of this site accessible to all. To accomplish this, we designed the site to comply with internationally accepted standards as set down by the Web Accessibility Initiative (WAI). This has enabled our pages to meet high accessibility standards. We review and improve the sites conformance to these standards and guidelines using online validation tools and manual checks. We also actively act on the latest authoritative advice and feedback from our visitors.
For conformance to W3C recommendations we use XHTML 1.0 Transitional structured semantic mark-up and Cascading Style Sheets (CSS level 2.1) for visual layout. This ensures that the site supports as wide a range of browsers as possible and allows users of all abilities (including those with a visual impairment or physical disability) to access the site. The content of each page is still readable if your browser does not support style sheets.
We use relative font sizes, compatible with the user-specified "text size" option in visual browsers. You can also increase and decrease text size by using the zoom function on modern browsers. To increase text size use Ctr++. To decrease text size use Ctr+- and to reset text size use Ctl+0 (number zero).
This website provides a consistent navigation system:
- You can return to the home page at any time by clicking on the HOME button.
- We display the primary navigation links along the top while secondary navigation links are down the left column.
- We display useful quick links relevant to the section visited down the right column and popular quick links for the complete website down the left column of the page.
- Links have title attributes that describe the link in detail, unless the text of the link already fully describes the target (such as the headline of an article). The link text is written to make sense out of context.
- All pages include a search box and a link to a sitemap.
All content images used in this site include descriptive ALT attributes. Purely decorative graphics include null ALT attributes.
