This is a "face lift" update of the entire web site. The objectives are:
- to make the style of the whole site more consistent and visually more useful & attractive
- to improve navigation across the web site, especially to make it easier to get access to all of the material available
- to make it easier to develop the web site and evolve its appearance in future
The main method to achieve this is (for the first time) to use "cascading style sheets" (CSSs). All pages now use (linked) CSSs, and perhaps 80% or more of the styles throughout the whole web site are now determined by these style sheets.
An additional change is that all content pages now provide easy access to the Site Map, and hence to the entire content of the web site.
