Remove white space header-content

Hi,

I started using Agama Pro for my blog and made some WP Layer slides for static pages. When published there’s a white space between the slide and the header. The custom css I used for another theme doesn’t seem to be working.

Can someone provide me with some additional css to get rid of the white space?

Kind regards,

Pepijn
