Theme Horse

I also found this one:

#access {
margin-bottom: 10px;
}

And this to control all the excess space:

.hgroup-wrap {
padding-bottom: 0;
padding-top: 0;
}
#access {
margin-bottom: 0;
}
.hgroup-wrap img {
margin-bottom: 0;
margin-top: 0;
}

Put then one by one in the custom css and see the changes and adjust the values as you like.

I am still needing to dump the search and all the space above the header or at least control it.
