Hi!

I love this theme and appreciate what you guys have done.
I'm trying to add a snippet of css code to my site, but not sure which file to attach it to. Here's the code:

#node_product_full_group_inside_pages .field-type-image {
float: left;
padding-right:10px;
padding-bottom:10px;
}

This is for an Ubercart page (node type: product), a field group (group_inside_pages) which should make the five images in the group float to the left. I'm not sure where to put it. I've tried what I would assume would be the logical files (base.css in the nucleus base theme, for example), but I cannot make it work. Maybe I'm missing something, since I'm pretty inexperienced with CSS.

Not trying to get you guys to check my code, just wondering where I should place it?

Thanks.
