Help footer and gradient background

This is my newly mounted blog, as a slight variation of WordPress Default: re-Think

…if you look at the footer (png, with border transparency) you will see it has a background that overlaps the gradient background beneath it.

The problem: I have found no way of making the footer blend into the gradient serving as background for the page. I can remove footer’s background but then I see content’s repeat-y png, which seems to layer between footer, and bottom gradient. Don’t know how to explain it better…is it clear?

After intense searching, sleepless nights, and playing css detective, I must give up. Being a newb I am probably missing the most obvious solution, so please be kind.

Thanks in advance!
