Fixed nav bar assuming margin?

I was messing around with some of the lesson files and adding a fixed horizontal nav bar at the top. For some reason, there is about 22px worth of margin added at the top of the "nav bar" but I have no idea why... I thought that fixed positioning is relative to the viewport?

That is due to a browser default that puts a top and bottom margin on all ul items. If you use a css reset it would be a cross browser efficient way to correct the issue moving forward. If you would only like it for the fixed nav then set margin to 0 on the nav class.

.nav {
  background: #fff;
  color: #000;
  margin: 0;
  position: fixed;
  top: 0;
  width: 100%;
  z-index: 30;
