I have looked at this for so long maybe someone else can see why her CC class set is not working.

Is it the cloud class you are referring to?
If so, there are a few problems. The main one is that there is an extra } on the line above it in the stylesheet. That is causing problems for all css codes that follow.
Then, have her be careful about her declarations as well. For example: text-decoration-color is not the color of the text … it should just be “color”.
Otherwise, she is doing well!
