Difference Between HTML and DHTML
FREE
What is HTML?
HTML is an abbreviation for HyperText Markup Language. It is a mark-up language used to construct web pages and web applications. We can use this language to create the layout of our static page.
- This language is only used to represent data and not to transfer data. HTML is a combination of Hypertext and Markup Language.
- The link between web pages is defined by hypertext, while a markup language is used to define the text document within the tag that specifies the structure of web pages.
- Tags are the words that appear between < > and distinguish standard text from HTML code.
- The data are displayed on web pages in tables, images, diagrams, etc.

What is DHTML?
DHTML is an abbreviation for Dynamic HyperText Markup Language or Dynamic HTML and is distinct from HTML. This language is built on the HTML, CSS, Javascript, and DOM (Document Object Model) features that aid in the creation of dynamic content.
After the entire web page has been fully loaded, DHTML (Dynamic Hypertext Markup language) allows multiple scripting languages in a web page to change their variables that enhance the appearance and other functions.
- It is a collection of technologies used to create animated and interactive web pages that are created in real-time.
- DHTML facilitates user interaction by animating text and images in documents.
- It enables programmers to apply effects to their pages.
- It also enables page designers to include drop-down menus and rollover buttons.
- This term also describes the development of numerous browser-based action games.
- It also includes the ticker on many websites that require automatic content updates.
Components of DHTML or Dynamic HTML
DHTML is made up of four languages or components:
- HTML 4.0: HTML is a client-side markup language that is a key component of DHTML. It defines the layout of a web page using various defined basic elements or tags.
- CSS: CSS stands for Cascading Style Sheet, and it allows web users or developers to control the style and layout of HTML elements on web pages. The CSS rules for DHTML will be changed at several levels with JS and event handlers, adding a substantial amount of dynamism with very little code.
- JavaScript: JavaScript is a client-side scripting language. A variety of browsers support JavaScript technology. DHTML accesses, controls, and manipulates HTML elements using JavaScript technology. Statements in JavaScript are commands that instruct the browser to perform an action.
- DOM: DOM is an abbreviation for Document Object Model. It is a method of manipulating static content. DOM is a W3C standard, which is a standard programming interface for HTML. It is mostly used to define the objects and properties of all HTML elements. The only issue is that the majority of browsers do not supportDOM.

Note: DHTML is often confused with HTML as a language; however, it is not. It should be noted that this is an interface or browser improvement feature that allows access to the object model via Javascript language, making the webpage more interactive.
Difference Between HTML and DHTML
We have seen a brief introduction to the HTML and DHTML languages. We will now look at the differences between HTML and DHTML languages. The following table summarises the differences between these two languages:
| HTML (Hypertext Markup Language) | DHTML (Dynamic Hypertext Markup Language) |
|---|---|
| HTML is a mark-up language. | DHTML is a collection of technology. |
| HTML is used to build a static document page and to specify the hyperlinks. | DHTML describes the technologies used to build dynamic and interactive web pages. |
| HTML does not include server-side code. | DHTML includes server-side code. |
| HTML is a simple static page with no JavaScript or styles. | DHTML is a dynamic page with HTML, CSS, DOM and JavaScript. |
| HTML files have the.htm or.html extension. | DHTML files have the .dhtml extension. |
| HTML does not require database connectivity. | DHTML may require database connectivity as it interacts with the user. |
| HTML pages do not use event methods. | DHTML pages make use of event methods. |
| HTML provides tags such as <body>, <li>, <form>, etc., to control the presentation of information on the web pages. | DHTML enables the incorporation of minor animations and dynamic menus into Web pages. It employs events, methods, and properties to provide dynamism to HTML pages. |
| HTML does not permit changes to the current pages without returning to the webserver first. | DHTML also allows you to modify the current pages at any time. Without initially returning to the webserver. |
Conclusion
- HTML is used to create the layout of static web pages, whereas DHTML generates dynamic web pages such as animations and dynamic menus.
- Compared to DHTML pages, HTML sites are considerably slow regarding client-side technologies. DHTML stands for Dynamic HTML and is completely different from HTML.
- HTML tags are the fundamental building blocks of all websites. It is also capable of producing interactive forms. HTML also allows you to create organized documents.
- This is accomplished by indicating structural semantics for text elements such as headings, paragraphs, lists, links, quotations, and other objects.
- DHTML also allows the pages to alter at any time without reconnecting to the Web server. It enables scripting languages to alter the appearance and functionality of a web page after it has been fully loaded and while it is being viewed. It also enables the user to add difficult-to-achieve effects to their pages.
