Let me know if you can reproduce the above design.

I am running into trouble with `./setup.sh -d -u shashi` docker error log contains:

```
Traceback (most recent call last):

I have a hack that injects CSS into the iframes: this is pretty lousy since navigating to a different page in the iframe removes the injected styling. I am hopeful this could be fixed.
Oh, yes! Fixing this. The height gets automatically adjusted in JavaScript, so I could just remove it.
