Yes but today Muse does not handle correctly the horizontal scaling of a whole page (only some objects). So forget Muse if you want the HTML to fit landscape/portrait orientations like a "standard" HTML page. Fixed DIV is not really the best method for multiscreen design and production.
In the words of Leanord "Bones" Nemoy from Star Trek, "Damnit, Jim, I'm a designer not a coder!" Now if DPS used BASIC, I'm down for that, I could do that, but I doubt they do and my HTML is about as good as my Japanese. End of line.
