Basic HTML Template for Designers to create a Style Guide

When I start a new front-end project coding HTML/CSS I will ask the designer to provide a style guide to outline the typography used through the website. I find when I mark-up the CSS for the typography first, before starting the grid, the overall CSS is cleaner. How do you communicate what elements need to be in the style guide? Well there are some basic elements such as headers, forms and table that I provide in a HTML file that the designer can start with. Then additional typography elements, such as typography in sidebars and call-to-actions are added to the style guide. Are there any elements you think need to be included in my basic HTML file? I like to keep it relatively simple so I don't add things like definition lists, but perhaps I should. Let me know.
