Let's say there are three paragraphs, each with the class "paragraph."
Then a subclass for each one is made because I want the color of text for each paragraph to be different, so the subclasses are red, yellow and blue.
Now that the subclasses have been established how can an overall class change be made? For example, let's say I now want to change the font for all three paragraphs. How can that be done since each the overall "paragraph" class now has a subclass stuck to it?
