Dynamic HTML is a collective term for a combination of
new Hypertext Markup Language (HTML) tags and options, that will let you
create Web pages more animated and more responsive to user interaction than
previous versions of HTML. Much of dynamic HTML is specified in HTML 4.0.
Simple examples of dynamic HTML pages would include (1) having the color
of a text heading change when a user passes a mouse over it or (2) allowing
a user to "drag and drop" an image to another place on a Web page.
Dynamic HTML can allow Web documents to look and act like desktop applications
or multimedia productions.
The features that constitute dynamic HTML are included in Netscape Communications'
latest Web browser, Navigator 4.0 (part of Netscape's Communicator suite),
and by Microsoft's browser, Internet Explorer 4.0. While HTML 4.0 is supported
by both Netscape and Microsoft browsers, some additional capabilities are
supported by only one of the browsers. The biggest obstacle to the use of
dynamic HTML is that, since many users are still using older browsers, a
Web site must create two versions of each site and serve the pages appropriate
to each user's browser version.
