Hi, at worst you can use a script and temporarily change your css to and have some snow and some red element, also don't take too much the head because the fetes only last 1 month well it's true that it's been 30 days anyway and that on the thread of a year it's long but despite everything to modify her skin for this I find that it's too much of a headache I prefer on my side to stick to the temporal version ^^
