Test Page H1 or H2?

Image of beauty

Hello World This page title should be invisible as H1 as been set to 0em. But here is a page title in H2 format.

The idea is to remove the title and replace all titles, pages and posts, with decorative images. This is ruined by the presence of any page/post heading. So now the damn thing has to be removed again and all H2 settings removed to H3, and all H3 removed to H4….

Theme Child of Responsive (current version installed is 3.16.4)

This is supposed to be H2
