long-time css criminals are aware of the fact that the only way to do css animations in a post is to steal one of the animations from the site itself, and a lot of people specifically like to use the bounce animation for silly purposes
people have also noticed that the site doesn't actually use it for real anywhere
the secret: we use it for a special element in the top nav that only appears when your session is wearing "mod mode"
my original design intent for making it bounce is
- it's an animation our CSS framework comes with for free
- it's extremely obnoxious, which reminds you to turn mod mode off as soon as you finish doing work
