Menu Disappears in Mobile

So I’ve been being conscious in bouncing between desktop and tablet, but when I goto my mobile view my menu disappears which is usually seated at the top. I’m trying to find out responsive options to fix it to adapt, but not having any luck. Is there a tested solution to get things constantly working across all dimensions? Thank you!

Solved, I found the magic which is the hamburger symbol and just had to switch from light to dark view. Thanks again!
