Site Personalization : Font & Background

Question

I have a website with a masterpage and a page called personalize.

I Want to change the background image of my site using a dropdownlist from that page. My current background and font are defined in my body

Any idea on how to change my background and font?

Answer 1

Have the Master page define (public?) a variable for the background image, and have it set a "default" value.

Give the Personalize page the dropdownlist, and in the OnChange event for that list, set the background image variable.
