is it possible to make HTMLFragment of an entire DOM?

Creating an HTMLFragment of an entire DOM is not directly possible because DocumentFragment objects are meant to be lightweight containers that do not include the <html>, <head>, and <body> elements. They are designed to hold a portion of the document structure that can be manipulated and then inserted into the document without the overhead of being part of the live DOM tree1.

However, you can create a new Document object which represents an entire HTML or XML document. You can manipulate this Document just like you would with the main document DOM. If you need to create a fragment that includes the entire structure of a document, you would actually create a new Document rather than a DocumentFragment.

Here’s a simple example using JavaScript to create a new Document:

JavaScript

// Create a new document
var newDoc = document.implementation.createHTMLDocument("New Document");

// Set the contents of the new document
newDoc.documentElement.innerHTML = '<head><title>New Document</title></head><body><h1>Hello World</h1></body>';

AI-generated code. Review and use carefully. More info on FAQ.

This creates a new HTML document with a <head> and <body> element, which you can then manipulate as needed. Remember that this new document is separate from the main document displayed in the browser window2.
