3,686 Points.content why does this div class exist within this page?
Within the index.html file the div class is present with an attribute of clearfix, I think understand why the clearfix, it's there so that the picture are separated from the header.
But is there any other reason why this is the parent div class of this section?
<div class="content clearfix">
<div class="photo-container">
<div class="photo">
<img class="side-a" src="img/photos/1.jpg" alt="Dazzling Auroras over Earth">
<div class="photo-desc side-b">
<h3>Dazzling Auroras</h3>
<p>Aenean lacinia bibendum nulla sed consectetur. Fusce dapibus, tellus ac cursus commodo.</p>
<a href="#" class="button">download</a>

So from that, it sounds like a wrapper div is a requirement.
