Why would you include a "normal" or "none" value into your css, since it changes nothing?

Answer 1

Based on what I've learned in the html course.. If you have a certain style in CSS that covers for instance all <p> , but you want one <p> to be an exception, that's you apply the 'none' to override the default you've set.

Answer 2

to prevent inherited element and go back to normal style
