A Very Good Question...for which I've used a compromising solution...
I currently have 3 websites that are using the Advanced Guestbook and have still not by any means mastered the environmental and style preferences. The closest I've been able to come to achieving the desired appearance is by using an Inline Frame. I ended up building a totally separate webpage utilizing an inline frame then accessing the guestbook URL through the Inline Frame. It works but I was hoping for something simpler and more efficient.
I am recent newcomer to these Forums and my primary reason for coming was to learn more about the Advanced Guestbook. So far I have not been able to locate the desired information though. Since I am new to the forum, and not sure of their policy on posting links, you are more than welcome to send me a private message, if you are interested in seeing what my guestbook looks like using Inline Frames, and I’d be glad to give you the URL.
Have a good day.
