your're missing the index value on the body element const body = document.getElementsByTagName("body")[0];

or you could use document.body or document['body'] to access the property of the document object.

You can't use getElementByClassName because body isn't a class, it's the html tag name. You could use document.getElementsByTagName('body') which will return a collection containing the single body element.

Or you could do it the easy way and use document.body
