Yep, CSS is good. If your template is very CSS heavy, eBay will sometimes strip it out when a user revises a listing. We have found the way around this is to actually have your styles at the end, after all of the HTML. For an example, view the source on this template. We had also heard that absolute positioning was going to be disallowed in eBay's new listing page, but so far no reports of broken templates (knock on wood).
