A children element is a tag, in this case a <p>, wrapped inside another tag. As a broad example, every tag on an html file/page is a children of the <html> tag. In the example below, the two <p> elements are children of the <body> tag (the “parent” element).

<body>
<p>Lorem ipsum</p> 
<p>dolor etc..</p>
</body>
