While visiting the W3C to validate a page I came across an old Style Guide mini site by Tim Berners-Lee from 1995 titled, Style Guide for online hypertext.
The document was written in the early days of the web, defining such terms as “webmaster”, the “www” and “.com” convention, and a few others. The mini-site has not been updated and remains an archive.
It was interesting for me to see how topics such as readability, usability, etiquette and web standards is discussed in the early days of the internet.
