John Power's site was constructed by Nick Keighley (which just goes to show you should never have your web site set up by a man you met in the pub!). It was prepared using a text editor in raw HTML and uses Cascading Style Sheets. Some lip-service was paid to the newer XHTML standard. This has the downside that it may not display well on older browsers.
Much reference was made to "HTML With XHTML and CSS" by Elizabeth Castro [link] and to the Web Style Guide.
Nick makes a living programming computers for some really quite
interesting Telecommunication Systems
