Unfortunately, there are not system variables to insert around in places like this. CSS just changes style of existing content (I know you can technically add text, but it is hard coded without using scripts, and really not a good thing to do generally). 

The closest I’ve seen for this was not on a course, but on a custom page using the user profile widget, and then customizing the widget.

Also, depending on the info, could use the scorm or similar connection to send info to the course package to display in the course package itself.
