how to prevent sticky opaque header and easy slider overlapping?

Hello,
I am not finding where this question has already been answered:

I am wanting to use a sticky (non-transparent) header with an easy slider as the first item in my main content, without having them overlap at all, but I dont see a way to control this in the theme settings.

The caption text of the easy slider is vertically centered on the slider image, but because the top of the slider image is partially covered by the opaque header, the text no longer looks centered vertically. How do I force the top of the easy slider to be flush with the bottom of the header and make the entire slider image visible?

I believe I know how to do this with a color section, and I can see this being done in the Enfold demo, so there must be a way.

thankyou (again)
