Aligning the horizontal menu

I added my horizontal menu without any problems but there is a gap between the blog roll and the menu. This led to an unexpected negative space.

So I played with the CSS to join them together. The blogroll is also a widget which can be selected by

#Blog1 selector. So I redefined its top margin.

#Blog1{
margin-top: -35px;
}

The negative value I gave pushed the blogroll up, which eventually helped to have a continuous look.

I still have the problem with the labels gadget. I must find a way to fill up the gap when I delete that gap. Still thinking about it.
