"In style.css, replace the three background image declarations with a single background property that reuses the same values."
background:url("https://s3.amazonaws.com/codecademy-content/courses/web-101/unit-8/htmlcss1-img_bicycles.jpeg")no-repeat center bottom;
I get the response:
"Did you set the background URL in one line using the background property?"
Not sure what the problem is. Wish I could just skip and go on to the next task.
