I'd consider looking at the User Banners instead of the titles from ladders as a starting point. There is existing code there to allow custom css and you can create all your own banners with whatever styling you want, including images. I don't even use the Ladder titles, I use a Title override in the groups based on post count (or whatever you want) so that the default ladder titles are never shown. That way I can always assign a banner (which could be anything you want, not specifically a "banner")
Yes I know this group styling page
But when I understand it right, I would have to create for every User "Rank" an own group.
It is not possible to use the group REGISTERED and just write css code where you can specify conditions like
when 10 Trophies --> use this style
when 50 Trophies --> use that style
I have to create for every of this conditions a own group and style this group.
Is my understanding right
P.S. In Xenforo_model there is the class UserTitleLadder.php
public function getUserTitleLadder()
But I don`t find the position of the function call,...
