2,867 Pointsfooter a {} versus .social-icon{}
Nick stated that declaring class="social-icon" in the anchors of the footer was done to show how a class can be used multiple times on a given page as opposed to declaring a single unique ID. He stated that when modifying the the footer we could have simply referenced the anchors nested within the footer (e.g. footer a {}). I had this thought prior to watching the video and tried it, but it didn't work so I assumed I had done something incorrectly. Then Nick said the same thing in the video, so I tried it again:
footer a { width: 20px; height: 20px; margin: 0 5px; }
It did not produce the same results as:
.social-icon{ width: 20px; height: 20px; margin: 0 5px; }
Why?

with .social-icon {} you are targeting only the elements that have the class of "social-icon".
Does that answer your question?
