The basic idea is to create a page that gives the user the ability to choose a skin or theme from a menu. When the user selects the desired skin/theme, it should be applied to the page, just like the jquery ui theme roller page.

So, to be more precise, what I am trying to know is how to apply dynamically the style to a page - how to load the css and so forth. On the jquery ui theme roller, is there any javascript triggered after the new set of styles is loaded? (for js positioning or sizing?)

(The answer may be simple as "just create a new style element and set its src"...)

Just to be clear, I don't need the option to let users customize the UI, I want them just to be able to pick from a few pre set styles.

Thanks!
