mobile view of WordPress gallery messed up

I placed a header 4 section on the top of the home page
I added a header 1 for the title of the gallery (WordPress nothing special as fare as a gallery software)
when viewing with an iPhone 6 with safari only a few of the pictures show up and they are on top of the text for the heading 4.

thank you for any help
