css can you reference an element withen an element

The title might not make sense, but I wasn't sure how to word it.
Lets say I have the following code (which is auto generated so I cannot supply an id or class in the caption element)
I can say in CSS
But I was really wondering if I could do something like
Or in some manor refer to ONLY caption elements that come inside an element with the id "gvClientTracking" (or elements with class "gv" would be ok too)

I really though I had read about this once, but cannot figure out how to look it up now.

Is that possible, or am I getting it confused with some xml styling abilities?

re: css can you reference an element withen an element

Yes you can using CSS "selectors". Unfortunately, they only work in modern browsers and not Internet Explorer though IE7 can handle a few of them with bugs. I'm heading out the door so here's a link to the spec or you can google for a tutorial on it. Here's a link to what works in which browsers.

Hmm well the goodnews for me is it works in ie6/ff3/chrome.2 with the
selector type. That should handle everything I need for this instance.
