footer 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 the footer a {} you are targeting every link the footer.

with .social-icon {} you are targeting only the elements that have the class of "social-icon".

Does that answer your question?

I will add that it would be eaiser if we could see the html and css code you are talking about. you can check the markdown cheatsheet at the bottom of this page to see how to post code in to the forums.

I think the issue is that the social-icon class was applied to the image elements not the anchor elements. If you used footer img {} instead of footer a {} it should work the same as .social-icon {}.
