Question: 1 / 400

What is the root node of an HTML document's DOM?

<body> element

<html> element

The root node of an HTML document's DOM is the <html> element. This element serves as the top-level container for the entire HTML structure of a web page. All other elements, including <head> and <body>, are considered descendants of the <html> element. As the root, it establishes the document as an HTML document and provides the necessary context for the browser to interpret and render the subsequent elements.

When a browser parses an HTML document, it creates a tree-like structure known as the Document Object Model (DOM). The <html> element is at the very top of this hierarchy, and it encompasses both the <head> and <body> elements. Within the <head>, metadata about the document is specified, such as title, links to stylesheets, and scripts. The <body> then contains the content that is displayed to the user.

Other elements, like <div> or <body>, while important parts of the structure and functionality of an HTML document, do not serve as the root node. The <head> element is also pivotal, but it is a child of the <html> element, further illustrating that the <html> element is indeed the root of the DOM structure.
