Help With Mobile Menu

Hello,

New to Webflow and I’m enjoying it so far. I’m looking for help with a couple issues with my mobile menu (currently testing on vertical tablet first).

I would like the background color (currently white) to fill the whole window. I almost have that working by setting the wrapper around the links to 100 VH. The issue is that it doesn’t extend to go behind the nav bar. I want the nav bar to be transparent on mobile like it is on desktop, but when the mobile menu is opened, I’d like the background color of the menu to extend behind the nav bar (keeping the logo and hamburger menu (close) button visible. As is, the nav bar stays transparent and you can see the website behind just that area. Reference image included.

I would like the navigation links to be horizontally and vertically centered within the browser window. I’ve tried a few suggestions and can’t get it to work correctly.

Thanks so much for your help!
