Another pseudo-class selector is first-child, which allows us to select elements that are the first children of their surrounding element.

<html>
<head>
<style>p:first-child {font-weight: bold;}</style></head>
<body><div><p>I'm in</p><p>I'm not</p></div><div><div>I'm not even a paragraph</div><p>I'm not</p></div></body>
</html>
]]>

Great! In this case, we're selecting all paragraphs that are, well, the first children of their parents.

While :hover is a valid pseudo-class, didn't we want to try :first-child?
