Introduction

DHTML is based on thinking of a web page like a printed page: a document that is rendered once
and that is static once rendered. The idea behind Dynamic HTML (DHTML), however, is to make
every element of a page interactively controllable, before, during, and after the page is rendered.
This means you can make things move, appear and disappear, overlap, change styles, and
interact with the user to your heart’s content. Through DHTML, users get a more engaging and
interactive web experience without constant calls to a web server or the overhead of loading
new pages, plug-ins, or large applets.
