Remove everything to get blank page

Hi. I am new to WordPress and I need help customizing the Customizr theme. I am working with Customizer Child and have managed to remove almost everything from the page based on code I have found in the forums, but I still have one remaining item I can’t removed. My Web site is http://www.winjohnnysipad.com so you can see what is still on the site. It seems to be particularly troublesome on the mobile site because it seems to be blocking part of the site that I created. Does anyone have any suggestions as to how I can get rid of the last of it so I can have a blank page? Thank you in advance!
