Aspen Child Theme

Child themes are generic – http://codex.wordpress.org/Child_Themes

But CSS is theme and site specific – so copying from someplace else won’t likely work.

But for help with Aspen theme, see:

EDIT – generic – but the code in the header of the style.css file must be specific to the theme being used.

His post merely says that there IS support on his dedicated forums here:

http://forum.weavertheme.com/

(And he has a reputation for excellent support :)!)

BTW, one reason you don’t see many (if any) threads on that theme is that it is quite new and because he provides support on his own forums (several other developers do that as well – it actually works to your advantage).
