Something is wrong !

Hey ! I have this problem with a new design Im on.
It makes 5-10px space between logo and the menu.
Well, it is better when you see it "alive", so here it goes:

And another problem is when I put !DOCTYPE in, the height wont fit!

Can someone see the mistakes, besides "background=" (If I dont use that,
it wont work :S)
