Web Design Guidelines and Standards

Dear Lazyweb, what should I put in a website style and branding guide?

When I'm developing software applications I am used to producing a number of guidelines that should be followed during development. These usually cover:

  • Architecture - these are the parts of the system and how they interact
  • Tools - these are the things you will use to build the system
  • Coding standards - these are the practices you should adopt with the tools we are using
  • Design - this is how the application will look and interact with people

I'm currently building a web site and struggling to find good examples of the last part. We have graphic designers engaged on the project but they don't have any templates to work from so we need to come up with our own. I don't want to re-invent the wheel so can anybody recommend a good template for a web site style guide?

I have found a couple of examples on the web, from Monash and Penn State Universities but would be interested in looking at any more that anyone can suggest.
