LOL. In your 2nd post you posted the wrong link and I went to your existing site. I should have spotted that, but instead thought, wow he's making changes really quickly, and was then able to interpret your request in that context as there is also a gap there between the same two elements albeit difficult to see with two dark backgrounds against each other!

However on the site that you are actually working on, the solution is different. The gap is most likely because you have a BR tag between those two elements and that has it's own intrinsic height.

You can either remove the offending br tag (probably somewhere in your tpl_header.php template, or remove it's height by adding
#headerWrapper br {line-height:0}
to your stylesheet.
