Step 52 Help: Either I'm misinterpreting the instructions or the course is broken

I’m having an issue with the flavor and dessert selector
The directions to this problem seem unclear…does the task require me to merely remove the word ‘flavor’ and replace it with ‘dessert’…because that doesn’t appear to solve the problem. Is there a way to apply two selector names to the same exact nest of properties simultaneously? The only hint offered isn’t of much help.

Challenge: Step 52

Link to the challenge:

“Since the flavor class selector already has the properties you want, just add the dessert class name to it.”

In other words, you want the ruleset for the flavor class to also be used for the dessert class, but you don’t want to make a separate ruleset for dessert, you want them both to use the same ruleset.

What the instructions don’t explain is how you add multiple selectors for the same ruleset. You separate them with a comma.

Thank you! That’s all they had to do…and to simply add a comma…now it seems like it should have been obvious.
