I am making a custom character sheet. As the GM, I want to be able to control the visibility of certain sections <div>s. As far as I can tell, the only way to do this is using CSS, specifically the :checked selector. I have players with pathological curiosity (and I mean that in a light-hearted way) that will muck with things and learn more than they should. So, I would like a way to hide the Attributes & Abilities tab from anyone not the GM -- so that even a player that controls the character cannot access the tab.
