@kvngzz,
Have you tried using HTTPS
in
"https://s3.amazonaws.com/codeacademy-content/courses/ltp/css/shift.css"

and
try using a capitalized shift
like
font-family: 'Shift', sans-serif;

After you made the changes do a refresh Browser
++++ reset of session *****************
As you are manipulating with objects
under certain circumstances you can shoot your Browser in an
inconsistent state.

Therefor it is of an advantage to know that you have 2 reset facilities:

One is the use of the F5-key which does a refresh Browser

and

Two, select&copy your code
Then use the Reset Code button of the course-window,
then paste your code back in.

Addendum
General Notes:
Always refresh the browser after making corrections:
CTRL f5 ( if on Windows or Linux)
CMD r ( if on a MAC).
