I love the travelify theme und try to use it for my sports club. We only want a header-image, no site-logo, no site-title. Unfortunately I do not know how to hide the container that holds them. The website is not online yet, have a look here: Screenshot
The white space above the header image dummy should be unvisible.
At first I want to reinstall the theme. Maybe I incidentally corrupted the style.css, though your patch is not working.
BTW: it would be a nice feature for travelify, if someone chooses “deactivate” in the theme option section for the header, that the container would be unvisible automatically.
