Definition and Usage
The body property sets or returns the document's body.
On return, this property returns the <body> element of the current document.
On set, this property overwrites all child elements inside the existing <body> element, and replaces it with the new, specified content.
Tip: The difference between this property and the document.documentElement property, is that the document.body element returns the <body> element, while the document.documentElement returns the <html> element.
