Standards compliance
  • All pages validate as HTML 5

Visual design
  • This site uses cascading style sheets for visual layout, meaning greater usability for assistive technology
  • The 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 stylesheets at all, the content of each page is still readable
  • Links have title attributes that describe the link in greater detail, unless the text of the link already fully describes the target. If you are using a mouse, or other pointing device, these can be viewed by hovering over the link text.

Pop-up windows

The use of pop-up windows on this site has been kept to a minimum. If a link opens a new browser window then this is explained in the title attribute of the link.
