Each page should use a CSS class in the form of page_name (I'm not sure how page_name is converted from the real page name to a class, so it's best jst to look at the page source). You can use this class to apply CSS styles, but you should know how CSS works to do this. I think it would look something like this (but I'm no CSS expert):
 * page_name
 * CSS stuff

I don't think there is an easy way to do this for an arbitrary range of pages without something like Javascript.
