On top of DrYoshiyahu's post I think the layout could be improved by adding the element style "max-width: 100%" for the container class. It uses the screen space better than the current default. I created a google chrome extension to automatically apply this change along with some coloring (to help with visibility). If we could get a variable selector like yoshi for the level leaderboard and this max-width change we would be grateful.

Here is a gallery of images of what I'm describing https://imgur.com/a/tGeAlCI
