[SOLVED] Space between header and main content

I've searched the forums, tried putting this in the inserts,

td#header {
padding-bottom:0px;
}

but still no luck getting rid of this.

I do have this

position: relative;
top: -55px;

to move my menu over the header image, however I've also change the menu height to 0, and it still didn't get rid of the space here.
Other suggestions I can try would be much appreciated! Thank you!
