The [hat](https://meta.superuser.com/questions/5878/you-like-them-hats) in users' profiles does not move with the centered page contents (including the gravatar) when the browser window is resized.

Demo in Firefox (Safari has the same issue), before and after resizing the browser window:

![Correct hat position][1]

![Wrong hat position][2]
