merged header issue on mobile

I've looked through the support threads but couldn't find something that worked for me... just trying to get the Home page header, logo and nav, to look the same as the sub-pages on this site - on mobile

I've disabled the slideshow on mobile... now just need the header area to have a black background, and the page content to drop below the logo/menu like on the interior pages.

Any CSS recommendations? I tried media queries with "clear:both" for the content, but nothing was working.

Thank you!
