I'm having a little trouble with the mobile versions of the site I've created. The backgrounds and, in some cases, the content height of the site appear different on a smartphone after the site has been uploaded to its url than it does in the editor. In the editor, there's every indication that the site will look normal, but as soon as I upload the files via FTP to my domain, the mobile site's appearance is radically thrown. Any idea what the issue might be? Incidentally, the desktop browser site functions perfectly.
