Transparent Header with simple slider

Hi!

I would like to use a simple slider with a transparent header. The problem is, however, that the slider is not at the top of the page, but shown right below the header menu. Thus: No full transparency.

It works well when I use the full screen slider, but I’d rather prefer the simple slider.

My question: Is there a way to use a simple slider AND a fully transparent header?

Thanks for your help!

Cheers,
Thomas
