Reduce padding for field labels

I've been using Firebug to try to find the right CSS to target, and have come up empty. I need to get the field label moved up closer to the field input. For example, I need "First" to be moved up closer to the first name entry box. I'd like to do this for all of the field labels in the form.
My form is viewable here:

The example field label can be viewable here: http://grab.by/kBMu

Thanks!
That send me on the right track.

I ended up using the below. Although if I have time, I still need to tweak the bottom padding so the field description is not right on the entry field below it.

.gform_wrapper .ginput_complex label{
	line-height: 1 !important; // this is the important one
	margin-top: 0;
}

.gform_wrapper .gfield_description {
    padding: 0px !important;
  	line-height: 1 !important;

}
