Parent & Child Elements

HTML elements have a hierarchical structure that involves Parent and Child relationships.


A Parent Element is a higher-level element that contains other HTML elements within it. The lower-level HTML elements contained within a parent are called Child Elements.

Parent and Child Elements
<!-- This div is the parent element. --> <div> <!-- This p is a child element. --> <p>Hello!</p> </div>

In the example above, the <div> element is the parent element of the <p> element, which is positioned as a child element under the <div>.
