Full page width

So, I noticed that on mobile, all of the content of the various sections are scrunched down even though I am using a full page width template. I found the “stretch using JS” option that can be set…section by section…but I have a LOT of pages I’ve already created and I don’t want to do this hundreds of times. Is there another global setting somewhere…maybe using CSS or even updating the database directly?
