While coding along with the video during the :empty explanation, I simply added an <h1></h1> with nothing inside of it. Yet, it did not turn the <h1> tomato as expected. Why is this? My code is below:
<!DOCTYPE html>
<html>
<head>
<title>Selectors</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link href='http://fonts.googleapis.com/css?family=Nunito:400,300' rel='stylesheet' type='text/css'>
<link rel="stylesheet" href="css/style.css">
<style>
body {
font-family: 'Nunito', sans-serif;
color: #616161;
padding: 40px 0;
}
h1 {
text-align: center;
}
ul {
list-style: none;
width: 50%;
margin: auto;
}
li {
border-bottom: 1px dotted #40918c;
padding: 15px 10px;
}
</style>
</head>
<body>
<h1></h1>
<ul>
<li>Item 1</li>
<li>Item 2 <span>✓</span></li>
<li>Item 3</li>
<li>Item 4</li>
<li>Item 5</li>
<li>Item 6 <span>✓</span></li>
<li></li>
<li>Item 8</li>
<li>Item 9</li>
<li>Item 10</li>
</ul>
</body>
</html>
BELOW IS THE CSS
li:first-child { background: #52bab3; color: white; }
li:last-child { border: none; }
span:only-child { color: #52bab3; font-size: 1.5em; }
:empty { background-color: tomato; }

:empty {
background-color: tomato;
height: 1em;
}

17,094 PointsThanks so much, Steven! That is the tricky thing about code: you can be using a concept completely right, but if you don't know all of the "side-effects" of an action, it can rob a ton of your time and energy and trick you into believing you are doing something wrong. Thanks for clarifying this for me!
