Dynamic HTML or DHTML is a method of creating interactive web sites by using a combination of static markup language (such as HTML), a client-side scripting language (such as JavaScript), the presentation definition language (e.g. Cascading Style Sheets ^*), and the Document Object Model. Some disadvantages of DHTML are that it is difficult to develop and debug due to varying degrees of support among web browsers of the aforementioned technologies and that the variety of screen sizes means the end look can only be fine-tuned on a limited number of browser and screen-size combinations. Development for recent browsers, such as Internet Explorer 5.0+, Netscape 6.0+, and Opera 7.0+, is aided by a shared Document Object Model.

Like LAMP, SPA, or Ajax, DHTML is not a technology in itself, but a term that refers to the use of a group of technologies together.

Though the term "dynamic web page" can refer to any specific web page that is generated differently for each user, load occurrence, or per specific variable values, those pages with this type of "dynamic" content should not be confused for DHTML. Web pages with this type of dynamic content, though still dynamic web pages, are a result of either server-side scripting (such as PHP), which generates unique content prior to sending the page to the visitor; or as a result of client-side scripting that is run immediately upon page load, before the static page content is visually generated. DHTML, as described above, is a term specifically reserved for those pages which utilize client-side scripting to effect changes in variables of the presentation 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. In effect, the dynamic characteristic of DHTML is found in how it acts and functions as each page is being viewed, not in its ability to generate a unique page with each specific page load.
