Document: head property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since June 2018.
The head
read-only property of
the Document
interface returns the <head>
element of
the current document.
Value
An HTMLHeadElement
.
Examples
html
<!doctype html>
<head id="my-document-head">
<title>Example: using document.head</title>
</head>
js
const theHead = document.head;
console.log(theHead.id); // "my-document-head";
console.log(theHead === document.querySelector("head")); // true
Notes
document.head
is read-only. Trying to assign a value to this property will
fail silently or, in Strict Mode, throws a TypeError
.
