3,675 PointsHow do you add a clearfix class to the main header? (challenge q)
It looks like we need a clearfix in the header. Give the main-header element the class we created for clearing floats.
<!DOCTYPE html>
<html>
<head>
<title>Floats</title>
<link rel="stylesheet" href="page.css">
<link rel="stylesheet" href="style.css">
</head>
<body>
<div class="main-wrapper">
<header class="main-header">
<h1 class="main-logo"><a href="#">My Work</a></h1>
<ul class="main-nav">
<li><a href="#">Design</a></li>
<li><a href="#">Coding</a></li>
<li><a href="#">Writing</a></li>
<li><a href="#">Hire Me!</a></li>
</ul>
</header>
<div class="primary col">
<h1>I'm a Designer</h1>
<p>I design beautiful user interfaces, then bring them to life with HTML, CSS, and JavaScript. I love including personal photographs of nature, people and everyday things in my designs.</p>
<p>If you need a front-end designer for your next project, <a href="#">take a look at my work</a>, then <a href="#">get in touch</a>!</p>
</div>
<div class="secondary col">
<h2>I Also Write</h2>
<p>I like teaching others about the latest web in technology. So when I'm not designing or coding websites & apps, you'll find me writing <a href="#">articles for my blog</a>.</p>
</div>
<div class="extra">
</div>
</div>
</body>
</html>

If so, it is just another class definition. The HTML element that has the .main-header class just needs to have another class added to it.
Any element in html can have multiple classes attached to them in the same way that .main-header was assigned to it. You would place it in the class="" attribute, separating classes with a space, like so:
<header class="main-header group">
...
I hope this helps explain it. Good luck!

17,211 PointsNo problem!
I didn't exactly know what the specific course you were taking was intending you to do, but there are always multiple ways to accomplish most things. Keep up the good work. :)

17,211 PointsI don't remember taking this specific quiz, but the way I described is one way to accomplish this and how I would do it.
That being said, they might be testing specifically in the CSS and ask you to do something to what you did with .group. I would suggest trying what I suggested, if you haven't already. If you have, try creating a .main-header:after css selector and copy the code from .group.
I hope that is not what they are suggesting, because that is the whole purpose of the .group selector.
