I don't know what i am doing wrong. Please help!
Your shift.css link looks okay, but I like to test links by following them in a browser to make sure they work. Have you done that? If you have, and the shift.css link is good, then we have to look in your CSS file.
I had the same issue and tested it in a web browser. It worked great.
That is a great way to troubleshoot by narrowing down the problem. Were you able to complete the exercise?
Unfortunately I could not complete the exercise because Codecademy keeps requiring me to 'add the link element for the custom font'. I was 62 % way through. And i can not proceed to other exercises because i keep being redirected to the same (unsolvable) exercise.
