Navbar Expand Up instead of Drop Down

Hello!

I’ve modified my nav bar menu such that it propagates along the bottom of the screen in tablet mode and smaller, but I’m struggling with two things:

1 - How do I make the hamburger menu expand from the bottom up (instead of the top down)

2- How do I set the hamburger menu elements to justify to the bottom right instead of the top right?
I set the menus layout to flex box justify bottom right, but this didn’t affect the layout at all. In fact, I had to set the nav-links to justify right to get them to justify right at all, which seems backwards to my admittedly limited understanding of the layout style options.
