I’ve been playing around with it, and it’s impossible to make it look good. So would it be possible for the Light menu to be the side menu and the sticky menu the normal menu? (you can see it at test2.sjoerdgerritsen.com)

Hopefully the screenshots should provide enough information.

I would like the menu the page starts with to be the one where you click on the 3 small lines that open a menu on the side. But once you scroll down you get the normal menu on top. Is this possible?
