3 jumbotron :make a website CSS styling


#1

this is what i have..

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

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

but then it says error and this happens
Oops, try again. Set the height of the <div class="jumbotron">..</div> to 500px

If someone could help me that would be great!!!
