Hi there, for anyone that' having problems progressing through the exercises on this part of the Sass course. If you think your code is correct, but codecademy doesn't seem to want to agree. I'd highly recommend attempting to run your code in different browsers.
I spent what in hindsight is a disproportionate amount of time pouring over my code (which was correct) only to hit several dead-ends.
In the end I switched (from chrome my usual browser) to for have the exact same code work fine.
