Custom CSS Code Simple Layout

Hi,

We have an NPS Question and we usually format the numbers to have colors to give some visual clue.

I typically use the following Custom CSS in other layouts but it does not function in the Simple Layout.  Any suggestions on how to apply or adjust this code to work in Simple Layout?

Thanks,
