My Google Chrome browser is set to 100% zoom and my font-size is set to 10px, but I still can’t get the challenge to pass to mark as completed. 
Below is a screenshot of me following the instructions you gave Troylrvo, but it didn’t work for me. I even tried to switch to Mozilla FireFox after Chrome didn’t work.
The solution on the Hint page is not working: freeCodeCamp Challenge Guide: Use @for to Create a Sass Loop
I don’t know what to do at this point.
