I was quoting your post not the quiz
Anyway all elements are display:inline by default until the UA applies its own styles so there is always more going on under the hood than you think.
Here’s another not so straight forward question.
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
<style>
table tr > td {
background:green;
}
table td {
background:blue;
}
table td:first-child {
background:yellow;
}
table > tr > td:first-child {
background:red;
}
</style>
</head>
<body>
<table>
<tr>
<td>Test</td>
</tr>
</table>
</body>
</html>
What colour will the td background be.
