"." is for classes that are in the HTML code that you or someone else created. You can create as many as you like and name them what you want. ":" is for certain states that are determined by the browser or other UI, like ":hover" when the mouse pointer over the element. There are only a set number of them and have predetermined names. They're called psuedo-classes because they act much like HTML classes but aren't the same thing.
