I have a question if this is possible to do:

Current behavior:
When we scroll down (on mobile devices) menu disappear and when you scroll up it appear again. I revived feedback from client that they have problem to see it.

Expected behavior:
When you scroll down or up - menu should be displayed always. Can you give me some hint how to do that ?


This is possible also to change color of that menu only on mobile for darkens (on site I'm using light one)?
