Can anyone explain this example of CSS syntax illustrated in the screenshot below?
My interpretation is that 'font:" is a selector and the remaining values up through font-family are qualifiers that can be used within selector "font:", but I don't understand what the other variables are and when they can be used. I've looked through all the W3c pages for an explanation but could find none. I'm pretty sure this an example of conventions used in the W3c tutorial on CSS but cannot interpret it.
