Spaces between sections in upfront

Hi. Just a note before I ask my real question: I select "general" because when selecting "theme" and then "spirit", message is not being sent. I tried 2 times.

So I try to remove spaces between sections with background images with no success. (spirit with upfront)

Solid colors seems ok but there's a problem with background images top. I've tried a couple of css things and section resize with no success.
