HTMLIFrameElement: contentDocument property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

If the iframe and the iframe's parent document are Same Origin, returns a Document (that is, the active document in the inline frame's nested browsing context), else returns null.

Example of contentDocument

js
const iframeDocument = document.querySelector("iframe").contentDocument;

iframeDocument.body.style.backgroundColor = "blue";
// This would turn the iframe blue.
