Hello, I'm puzzled by what it seems to be two pages with the same code and acting differently at the same time.
In the index.html the page behaves the way I want: the content adapts after resizing the browser but I get unusable space where header and content meets.
In the index2.html there's no unused space but when I try to shrink the browser the content element jumps off below menu.
Tell me if I need some sleep to find an error in the code because right now I see the code is 1:1.
