'''Dynamic HTML''', or '''DHTML''', is a term which was used by some browser vendors to describe the combination of [[HTML]], [[Style sheet (web development)|style sheet]]s and [[Dynamic web page#Client-side scripting|client-side scripts]] (JavaScript, VBScript, or any other supported scripts) that enabled the creation of interactive and animated documents.<ref>{{Cite web|title=Document Object Model FAQ|url=https://www.w3.org/DOM/faq.html#DHTML-DOM|access-date=2022-02-16|website=www.w3.orgW3C |date=October 22, 2003}}</ref><ref>{{cite web|url=http://www.w3.org/Style/#dynamic|title=Web Style Sheets|website=www.w3.orgW3C|access-date=7 April 2018 |date=22 July 1999}}</ref> The application of DHTML was introduced by [[Microsoft]] with the release of [[Internet Explorer 4]] in 1997.<ref>{{Cite web |date=2020-07-19 |title=DHTML {{!}} A Quick Glance of DHTML with Components, Features, Need |url=https://www.educba.com/dhtml/ |access-date=2022-10-13 |website=EDUCBA |language=en-US |first=Priya |last=Pedamkar}}</ref>{{Unreliable source?|date=November 2022}}

DHTML allows scripting languages to change [[variable (programming)|variable]]s 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. Thus the dynamic characteristic of DHTML is the way it functions while a page is viewed, not in its ability to generate a unique page with each page load.

A less common use is to create browser-based action games. Although a number of games were created using DHTML during the late 1990s and early 2000s,<ref>{{Cite web |title=Stephen's Web ~ Fun and Games With DHTML ~ |first=Stephen |last=Downes |date= Aug 18, 1999 |url=https://www.downes.ca/post/276 |access-date=2022-08-27 |website=www.downes.caStephen's Web |language=en}}</ref> differences between browsers made this difficult: many techniques had to be implemented in code to enable the games to work on multiple platforms. Browsers have since then converged toward [[web standards]], which has made the design of DHTML games more viable. Those games can be played on all major browsers and in desktop and device applications that support embedded browser contexts.

The term "DHTML" has fallen out of use in recent years as it was associated with practices and conventions that tended to not work well between various web browsers.<ref>{{cite book |last1=Ferguson |first1=Russ |last2=Heilmann |first2=Christian |title=Beginning JavaScript with DOM Scripting and Ajax |date=2013 |publisher=Berkeley, CA: Apress |pages=49–68 |doi=10.1007/978-1-4302-5093-7 |isbn=978-1-4302-5092-0 |s2cid=20526670 |url=https://link-springer-com.huaryu.kl.oakland.edu/content/pdf/10.1007/978-1-4302-5093-7.pdf |access-date=May 30, 2022}}</ref>
