W3C divides DHTML (Dynamic HTML) into three parts for implementation: scripting language (including javascript, Vbscript, etc.), browsers that support dynamic effects (including Internet Explorer, Netscape Navigator, etc.) and CSS style sheets.

External link styles can define multiple pages at the same time, greatly reducing the workload of repeated work.
