Sticky menu?

Hi guys.

I want to say first that I absolutely love the Oblivion theme – it’s awesome. I’m currently tweaking it for a big redesign of my existing site – http://www.continue-play.com (it uses Oxygen at the moment, but we’ve quickly outgrown it)

You can see the new site here: http://www.continue-play.com/testbed

We’ve managed to make the footer sticky (and we’re going to make it full-width as well)

My question is how we can do the same to the menu bar at the top? So no matter where you scroll on the page, you always see the top-bar menu and the footer. I added some css to the navbar element, but that didn’t work – and made it look a bit weird on Chrome (to say the least!).

Is there anything you can suggest to help me out?
