Site Tips: Branding SharePoint (WSS3.0 and MOSS2007)

Yesterday I started with branding SharePoint for one of our customers. Creating a custom theme is not that easy as it should be. I will come back later on that.
I found some useful sites on the internet. I want to share this one in particular with you:

• http://www.heathersolomon.com/content/sp07cssreference.htm

This is a nice overview of the used style elements in SharePoint sites. You can easily find the corresponding element that are used in the stylesheets ( e.g. .ms-topnavselected) by using the index or screenshots.
The main site, http://www.heathersolomon.com/blog/articles/sp2007.aspx, shows a lot of information about the structure and customizations of sites.
