links to buttons

Under "my courses" it shows a list of the courses you are enrolled in.
These are displayed as a link.
I would like to change the css class (style) of those links so that they look like buttons.
Would you know how I can override the code that determines the css class for only those links? It may be in the moodle theme.

Yes, you would just need to create a template override for the module.
You can see more info here:
