Ah, looks like my linking to a template preview could cause some confusion since it puts additional markup for presentation in there. Instead, go to the Listings tab and in the lower right click "Customize an Auctiva Template". Looking at template HTML there should give a clearer idea.
Unfortunately, inline styles could be removed as well if eBay ever chose to go that route. So just try and make such cool looking templates that eBay couldn't bring themselves to do away with them
