It might be easier to explain by showing you an example on Zaregoto. Long story short though: the infoboxes on both wikis were behaving normally as Wikia intended, before we used any CSS to modify their behaviour (there's nothing different about Katanagatari's base infobox or the CSS they're using -- the only difference is that it's not using  inside it on article pages). It's just that neither of their normal, designed behaviours are actually what you want (you're forced to choose between either having a background, or having no background but losing the ability to show more than one image per infobox).

If you temporarily cancel the CSS I gave you above and then check the example blog I just created at over here, you'll see two infoboxes:


 * 1) The first one is an exact copy of the one you linked in your opening post. This one should have a background colour around the image by default when you're not using the extra CSS to cancel it out.
 * 2) The second one has the  tags removed, which is what seems to be generating the tabs allowing more than one image to be shown in the infobox. This one shouldn't have any background colour by default around the image, and is basically what the Katanagatari infobox is doing (only displaying one image per infobox).

The moment you create tabs by using  in the infobox is when the background colour shows up, because that's apparently how Wikia wanted it to behave. The reason Katanagatari Wiki doesn't get that background (at least on the infobox example you linked) is because it's not using  to show more than one image -- without the gallery/tabs being generated, it won't generate a background.

While removing the  does bypass the background colouring, it also prevents you from displaying more than one image in your infobox, which seems to be a fairly important feature for your wiki. I don't really know of another solution to remove the background while also preserving your ability to show multiple images.
