Chapter 1 went over how to set up the 3 different types of HTML. You can combine selectors to make them all the same. You cannot reuse the same ID in the same HTML. These are used to style a piece of that page only once.  Classes are used to make the same style on many things instead of just one thing like an ID does.  The ID selector starts with a # instead on a . like a class does.
