I think there is a bug in the "visualizer" screen on the right side of the page for this exercise: https://www.codecademy.com/en/courses/web-beginner-en-WF0CF/3/5?curriculum_id=50579fb998b470000202dc8b
This is what I have in my CSS. But on the screen, only the 2nd link has a changed color, not the 3rd. I also tried changing the font-family. It also only affected the 2nd link.
a:nth-child(3) color: #FFC125; }
