I am running wordpress network and have several sites mainly using twenty ten (or twenty ten weaver) but also a couple of other themes as well. Premise is that predominantly one theme, bit not only one.
Is there a way I can define (just once) a set of CSS styles that will be inherited down the chain? I don't mind (and would like) to be able to further style them in each theme as appropriate, but generically, I would like to have them created in one place...
as an example, I might want to have a class for googlemaps, uploaded images and link styling that (as a rule) will be one way across all sites, but then able to be overwritten as required in each theme.
Is there a way to do this?
another reason for wanting my own styles separate is to avoid the main style being upgraded in an update
