Graphene uses Bootstrap as the grid system, so the mobile breakpoints follow the same as Bootstrap. In the case of mobile devices, it’s 768px. See Bootstrap’s documentation for the full list of responsive breakpoints.

Is there a way to prevent Graphene inserting the title line at the mobile breakpoint?
A plugin such as Max mega menu replaces the menu on the menu line with a hamburger and other options.
