Need Help responsive hanburger menu

Question

Hello, I'm making my first project in HTML/CSS/JS, but i've some problems with my code.
I can't align my menu on the center, I try putting it as a list, then, I succeed in algn it, but the responsive part doesn't work anymore.
Can someone explain to me how I should be doing this ?
(and I'll work after to make some dropdown submenu on it, if it's important. Already have some tutos and so one to make so, but none of them are responsive, so, that's a work in progress)
