header content all veertical

1. I installed a Pintrest HTML tag into the header.php. The entire header vanished and when I went to my c-panel file manager and looked at the page it was totally blank.
2. After talking to woo help I copied a clean page content of the header.php and pasted into the page that was blank. It worked, sort-of. Now the content is mashed up to the side and running vertical.
3. Next I changed themes in wp and completly removed (I think) the storefront theme from file manager in c-panel. I then reinstalled the storefront theme from wp. Every thing in the header is still squished up and vertical. I’m thinking the problem must be in wp but I really dont know squat about this stuff.
