I am working on a school project and I'm finishing up on a WordPress site. I'm trying to remove or hide this white space between my header and my footer. I don't want any content in between. The div in between is called div#content.page-wrap. And when I add: display:none; it gets removed. The problem is, it gets removed on all pages. So I'm looking for a way to remove bits of php from the front page, or to edit the class name specifically for the home page so only that one gets edited. The problem is, any changes I make make no difference in either the css cutomizer, editor or by editing and updating the php/css via filezilla. So I don't know if I am editing the right thing or editing in the right way.
