Jumbotron problem


Hey guys i got this problem:
It says i need to set the height to 500px but i already did that, what is wrong in my code?

.nav a {
color: #5a5a5a;
font-size: 11px;
font-weight: bold;
padding-top: 14px;
padding-bottom: 14px;
padding-left: 10px;
text-transform: uppercase;
.jumbotron a {
background-image: url('https://goo.gl/04j7Nn');
height: 500px;


Nope, you set the link inside your jumbotron to 500px in height. I would change your css selector
