Floating sidebar on top of fullscreen slider?

Hello,

I made a very simple homepage with a fullscreen slider. it looks great.

I want to have a sidebar (doesnt have to be a sidebar, just need some content) on top of the slider.

I cant find a way for doing this… can you please advice how can I make this happen?

Here is a screenshot of what I want:

I want content to be where the white window is.

Thanks alot in advance,
Amit.
