Margin between jumbotron and content increases when shrinking window

Question

I'm so close to finally getting my jumbotron image to shrink to fit viewport when resizing smaller, but now when I do it increases the bottom margin the smaller I make it. Easy fix?

I've messed around quite a bit with your code. The height: 600px for .jumbotron is throwing it off. Here's what I think you're looking for... let me know.

@media screen and (max-width: 900px) {
  body .jumbotron {
    background-size: 900px;
    background-position: left -50px center;
  }
}
.jumbotron {
    padding: 0;
  height: 90vmin; /* Here you can change the height */
  width: 100%;
    background-image:url('http://4.bp.blogspot.com/-CIy9X0Vwlko/VFvyStJbP_I/AAAAAAAACys/Ze7QVlcVmX0/s1600/HOPE%2BLogo%2Bcopy.jpg');
    background-repeat: no-repeat;
    background-size: 100%;
    background-color: #efeeec;
  background-position: left center;
  overflow: hidden;
    position: relative;
}
.jumbotron h1 {
      color: #fff;
      font-size: 60px;  
      font-family: 'Love Ya Like A Sister', cursive;
      font-weight: bold;
}
.jumbotron p {
    font-size: 30px;
    color: #A80000;
}
