What is wrong with my code it keeps asking me for font-family:'Shift', sans-serif on the jumbotron h1 selector


#1

p {
    color:#fff;
    font-size:20px;
}

.jumbotron h1 {
    font-family: 'Shift',sans-serif;
    color:#fff;
    font-size:20px;
    font-weight:bold;
}

.jumbotron {
    height:500px;
    background-image:url('http://goo.gl/04j7Nn');
}

.nav a {
    color:#5a5a5a;
    font-size:11px;
    font-weight:bold;
    padding-top:14px;
    padding-left:10px;
    padding-right:10px;
    padding-bottom:14px;
    text-transform: uppercase;
}

This part looks great. Let's have a look at your <head> ... </head> element.
