Function calls used in Theming

I've already created a couple of custom, advanced, ddblock themes, and feel that I have a pretty good understanding of the php and css involved. However a client has asked to have the pagers appear on top of the slide, as opposed to beside it. I have created the appropriate css to achieve this and it works fine in testing without any function calls. But once it's appearing on the website, the javascript is dynamically changing the z-index of the "slide" class. I'd like to see if I can get around this, or at least understand better what changes are being made, but can't figure out which function is adding the inline style info to the div class.
