I've done some research on here and I've found some references to inline styling. But I can't find anything that suggests that a CSS can be applied only at a specific course level. 

For example, we have two courses and want two different style guidelines for both. Say in Course B we want headers 2 through 5 to be bold/italic/centered/size 14 but we don't want that in Course A. Course A is happy being non-stylized. 

There's no way to assign a stylesheet that is specific to that particular course? I understand this can be done with div containers but I don't see that being a viable solution when you need it done to every content page.
