Document: body property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since May 2018.
TheDocument.body property represents the<body> or<frameset> node of the current document, ornull if no such element exists.
Value
One of the following:
Examples
js
// Given this HTML: <body></body>alert(document.body.id); // "oldBodyElement"const newBodyElement = document.createElement("body");newBodyElement.id = "newBodyElement";document.body = newBodyElement;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 thebody property is settable, setting a new body on a documentwill effectively remove all the current children of the existing<body> element.
