Over the past few days I've been trying to wrap my head around how to make the character infoboxes in this wiki collapsible (example right here) in order to make the character pages more tidy and organized. Unfortunately, I have absolutely no experience on CSS editing, so I would like to ask for the help of anyone who does. More specifically, I was thinking of having everything starting from the "Characteristics" field hidden. And of course, I take the opportunity to ask you guys how you feel about this.
Thanks in advance!
