Okay, so it looks like you’ve used code from one of the challenges and pasted it in the CSS box.
The goal of this project is to build your own tribute page from scratch. Using the code from that lesson will not help you, and might be part of your confusion.
Additionally, you need to include the test script in your pen. You can do this by going to the FCC Pen and clicking “Fork” down in the bottom right - then use that new pen it creates to build your webpage.
