Document: body property

{{APIRef("DOM")}}

The Document.body property represents the {{HTMLElement("body")}} or {{HTMLElement("frameset")}} node of the current document, or null if no such element exists.

Value

One of the following:

{{domxref("HTMLBodyElement")}}
{{domxref("HTMLFrameSetElement")}}
null

Examples

// Given this HTML: <body id="oldBodyElement"></body>
alert(document.body.id); // "oldBodyElement"

const aNewBodyElement = document.createElement("body");

aNewBodyElement.id = "newBodyElement";
document.body = aNewBodyElement;
alert(document.body.id); // "newBodyElement"

Notes

document.body is the element that contains the content for the document. In documents with <body> contents, returns the <body> element, and in frameset documents, this returns the outermost <frameset> element.

Though the body property is settable, setting a new body on a document will effectively remove all the current children of the existing <body> element.
