Dynamic HTML , or DHTML , is a term which was used by some browser
vendors to describe the combination of HTML, style sheets and client-side
scripts (JavaScript, VBScript, or any other supported scripts) that enabled
the creation of interactive and animated documents. The application of DHTML
was introduced by Microsoft with the release of Internet Explorer 4 in 1997.
DHTML allows scripting languages to change variables in a web page's
definition language, which in turn affect the look and function of otherwise
"static" HTML page content after the page has been fully loaded and during the
viewing process.
