Dear community,
I feel extremely dumb for not finding a solution to my problem which I’m trying to solve by myself for days… 
I’m a complete noob to webflow (and website building in general) so please be patient with me.
Here’s what I’m trying to achieve:
The soon to be floating nav bar (in the images represented by the black bar) shouldn’t be on top of the ‘background image’. But as soon as the canvas hight is too small, the background image slides right underneath the nav bar. The image has to be fixed to the bottom of the body.
I feel like there’s a simple and obvious solution to my situation. Unfortunately I’m not able to find it on my own…
Many thanks in advance for helping me out.
