there is this annoying white space between my header logo and nav. (well, where the nav would be, but I didn't want it to show.)

It's been there as long as I can remember and I've tried everything to get rid of it. I've gone through posts of other people having the same sort of problem, but nothing works for me.

I can see with the dev tools that my image height is 110px and the height of the black bar is 21px, however the total height from top of the image to bottom of the black bar is 143px. I can't find what to change to fix this.
