7/10 "Learn More" - I keep getting error "Oops, try again. Set the background-color of <div class="learn-more">..</div> to #f7f7f7"



I'm a little bit stuck!

I keep getting the error message for 7/10 "Learn More" - I keep getting the error "Oops, try again. Set the background-color of <div class="learn-more">..</div> to #f7f7f7"

I think my CSS is right, so I'm thinking there maybe is something wrong with my HTML code.

Here is my CSS:

.nav a{
    color: #5a5a5a;
    font-size:  11px;
    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;

.jumbotron h1{
    color: #fff;
    font-size: 38px;
    font-weight: bold;
    font-family: 'Shift', sans-serif;

.jumbotron p{
    colour: #fff;
    font-size: 20px;

.learn-more {
    background-colour: #f7f7f7;

And this is my html

<!DOCTYPE html>
