I don’t know what else to do. Can some check my work?
You need to add position of absolute, then adjust padding everywhere else.
position: absolute;
top: 0;
left: 0;
right: 0;
To your nav element you need to add:
position: fixed;
top: 0;
left: 0;
Also , I would recommend taking your nav element out of your header element and putting it above the header. Also add to the nav width 100% if you want it across the entire top screen.
Thanks for the help! I complety forgot about positioning. I still had to keep the nav within the header section in order to pass.
