Sidebar below content

Hello, go to the General Options > General Settings section of the customizer, in Content Widget and Sidebar Width, the total of the two fields needs to be 100%, right now you have added 100% to the content with, so the sidebar cannot be on the side. You need to add something like 70% and 30% for the sidebar so the result is 100%

Sorry.. one more thing… would it be possible to put featured image in the header of the post but without the title over it?
