      You can't see the text because of the overflow

                body {
  margin: 0;

/* Pretend the header (limegreen box) is the viewport
   it is set to 50% width so we can see outside it.
   Imagine if the left and right side of the green box was the viewport.
   You would not be able to see the left side of the orange box.
   To show the overflow comment out "overflow: hidden"
header {
  position: relative;
  background: limegreen;
  width: 50%;
  height: 40px;
  margin: 0 auto;
  /* comment out the style below to show the overflow */
    overflow: hidden;

nav {
  position: absolute;
  background: orange;
  width: 100%;
  height: 20px;
  right: 100px;
