Advanced Styling: Combinators

Selectors can be combined to make them more specific or to create interactions like "Buttons are blue, but big buttons are green."

AB matches elements that match A and B. - E.g. button.big. matches <button class="big"> - Note they are smushed together with no space

A,B matches elements that match A or B - I say "A comma B" - Note this is not consistent with how you list multiple attributes or classes on an element, where we have space separated lists. - I'm sorry.
