1. Compared with the descendant selector, the child element selector can only select elements that are child elements of an element.

2. The sub-element selector uses the greater than sign ">" as the connector.

Example 1:

<html>

<head>
    <style type="text/css">
        h1 > strong {   
            color: red;   
        }   
    </style>
</head>

<body>
    <h1>This is <strong>very</strong> <strong>very</strong> important.</h1>
    <h1>This is <em>really <strong>very</strong></em> important.</h1>
</body>

</html>
Copy after login
