Hello everyone. I'm a little confused on what exactly I need to do with my background property when using the compass url helper.
.featured-icon {
background-image: image-url('mixin-monster.png');
}
The message is suggesting that I "make sure I am setting the background property."

Courses Plus Student 94,610 PointsHi Andrew,
It looks like the only problem is that the start code used the background
property and you switched it to background-image
