DHTML was just JavaScript that mutated the DOM. That’s literally all it ever was. There was also not a DHTML doctype. There was also not anything even called “an extension”. There were Java applets, ActiveX controls, and ActionScript -> JavaScript bridges, which the concept of DHTML (dynamic HTML) eventually fully replaced.

Divs weren’t a “craze”. They were popularized by the (brand new) XHTML spec, which did have its own doctype.
