Hello! I’ve been experimenting with using a custom header or custom logo. I’ve made the logo small enough that it should be able to stay at full size even on mobile. However, I’m finding that whichever I use, the entire header area gets shrunk as part of the responsive action, making my logo or header image very small. If I want to make this area not be responsive, or if I want to change the settings, what in the CSS should I be looking for?
