What is the JS script for the visual HTML page editor?

Question

HTML

Hello.
I found an excellent version of the visual editor , but there is a problem that you need to mark up the page
data-editable-demo data-name="page__content"
. And I would like this option:
1. Save the HTML page of the site;
2. Insert the editor's JS file into it;
3. Open in browser and start editing.
