What Wikia does depends on the severity and frequency of violations. There is no publicly available explicit list of violations and consequences. However, for something such as this, I would imagine they would simply remove the offending CSS and give you a warning. I don't think they would close the wiki (or block you) over it. - Edit:

Of course, that is just my opinion. I cannot make any guarantees. Since the customization guidelines (as publically provided) are not entirely black-and-white, there is also the chance they will let it slide.
