How do I turn off the automatic shrinking of the header when scrolling?
There is an option in the theme customizer to where you toggle off the fixed header option. That can be found via Header > Header Layout > Fixed Header.
After looking at this again, I realize you may be looking at keeping it a fixed size? If so, you’ll need to do that with some custom CSS. Let me know if you need any help there.
Precisely. I want to remain the same size when scrolling down. What CSS do I need to add?
