Product Landing PageProject...Help!

Hi folks!

Utter beginner here,
Currently plugging away at the Product Landing Page Project. I’m forcing myself to use flexbox as much as I can and it has lead to an issue

I want all the items from my

    to splay across the bottom of my Nav container. I’ve tried justify-content: space-between; among a few other things and nothing is splaying out the items in the way I want.

    Any help would be greatly appreciated

    Thank you for taking the time out of your day to read this
