First of all: Thank you! That worked.
I struggle to see where I went wrong, I’ve tried quite a few different solutions where display:none; was in the picture. I think it may have been my selector, I think I used ‘.navbar-toggle collapsed’ (notice the space where you have a .).
I always use inspect function in to look up the element, but that is none the less great advice that should be included.
Thanks again, and have a great day o/
I still need help on this issue. The hamburger just won’t go away, not on mobile nor on narrow desktop browsers.
