How to get the <html> tag HTML with JavaScript / jQuery?

The simplest way to get the html element natively is:

document.documentElement

Here's the reference: https://developer.mozilla.org/en-US/docs/Web/API/Document.documentElement.

UPDATE: To then grab the html element as a string you would do:

document.documentElement.outerHTML

This is how to get the html DOM element purely with JS:

var htmlElement = document.getElementsByTagName("html")[0];

var htmlElement = document.querySelector("html");

And if you want to use jQuery to get attributes from it...

$(htmlElement).attr(INSERT-ATTRIBUTE-NAME);
