Accessibility

Links

Links to other websites and PDF files open in the same browser window rather than opening a new window. Visitors wishing to open a new window can hold the SHIFT key (Windows) or Control key (Macintosh) while clicking on the link.

Images

All content images used in this site include descriptive ALT attributes. Purely decorative graphics are implemented as background graphics in the cascading style sheet.

  • This site uses cascading style sheets for visual layout
  • This site uses only relative font sizes. Visitors may use the text size or page zoom facility of their browser to change the size of the text
  • If your browser or browsing device does not support stylesheets at all, the content of each page is still readable and is presented in the most sensible order.
