Try keeping the relative position for the div.logoheader
and also adding bottom: 35px;
. This should push it up. It's not the best method, however without seeing a live preview of the template, it's rather hard to give a more accurate answer. So your final code should look like this:
div.logoheader {
position: relative;
bottom: 35px;
}
You may need to change the value 35
according to the spacing. Hope this helps
