styles and child styles
 

I'm working on a template mod and wondering whats the point for multiple styles and child styles?

Even multiple styles (sets of the same templates) don't make much sense since ... ideally, you'd be able to customize the look w/ CSS (www.csszengarden.com). I think vbulletin's code doesn't have this much flexibility which is why multiple styles exist, but i'm not not sure what a good use for child styles would be? any examples?

Multiple styles exist so that your users have choice between what style they want to use. o_O

Child Styles exist so that you can use the same template code while being able to modify the CSS and colour settings of that child style.
