Difficulties with two div containers embedded inside another div

Hello I have some tags you will not recognize in html, however, it does work when I load it from my editor/processor (the tags that seem foreign). My main problem is that I have a div called wrap containing both menu and content divs. These divs has classes called panel and panel content (menu has panel content/content has no content class associated with it.)

The only thing I can do to make it display properly is to put an absolute tag on it.
