Yes, but I've not seen it on any other wikis. The RWBY wiki uses something similar; however, that one is equally as clean, but much more accessable. Check some of their character lists and you will see my meaning. If you really want cleaness over accessability, then get a damn Curse wiki page!
They use separate pages. That's an increase in load times, and makes accessbility weaker.
Warframe wikia used to do that too, until they realized it was awful for mobile users, since they wouldn't be able to see any of these sub-pages, which made up a majority of the wikia. They then started using tabbers, like us.
