Why can't floating AD/Couplet code be used in XHTML web pages?

Check the code of the couplet and Its Expression in xhtml. The result is very simple. This is because, according to the standard, the scroll bar of the form we see should not be the body, but the HTML (that is, the document.doc umentElement object), so the solution is: put the nonstandard code "document. body. scrollTop "is changed to" document.doc umentElement. scrollTop ", everything is OK!

(Failure scope: XHTML 1.0 transitional. dtd; XHTML 1.0 strict. dtd; XHTML 1.0 frameset. dtd; xHTML 1.1 DTD)
