Introduction to DHTML
DHTML stands for Dynamic Hypertext MarkupLanguage i.e. Dynamic HTML. DHTML and HTML do not compete with each other, but it can be said that DHTML is the extended version of HTML along with using different web technologies. The HTML helps build static web pages, whereas DHTML allows for designing dynamic web pages with more interactivity. It allows designing an intuitive, dynamic user interface along with animations. It is not a specific technology or a standard, but it is a concept where multiple other technologies are used together to achieve a result. These different technologies used in DHTML are known as components.
Why do we need DHTML?
Microsoft first introduced the application of DHTML in 1997 with the release of Internet Explorer version 4. Without DHTML, there used to be the use of only static web page. There are some incapabilities or disadvantages while using static web pages. There is no interactivity with static pages for the user. The page needs to be refreshed every time user wants some change. No dynamic actions can be taken on a web page without reloading it. The DHTML, however, provides the capability to achieve all of this.
The DHTML allows changing the web components dynamically on the client-side without reloading the web page. It provides a user with the flexibility to interact and change the values directly. DHTML allows us to change or alter the values and functions to perform differently according to the users. DHTML is a very broad concept; it will load the web page depending upon different users, load occurrence, or the values provided by users.
As said in the introduction, DHTML uses different web technologies together, and these are known as DHTML components. DHTML uses a combination of the below components to make websites interactive and achieve animations in a web site.
- HTML- Static Markup Language
- CSS- Style sheet Language
- DOM- Document Object Model
HTML is a client-side markup language that is used to design static web pages. HTML is the core component of DHTML. It defines the web page components to be displayed on a web page. HTML defines the structuring of components by using different elements and tags. HTML, however, allows to design only static web page; the user cannot change the values of elements dynamically at the client-side. But still, HTML is the basic component that is required to build a web site.
- DHTML allows creating dynamic web pages with ease and simplicity.
- DHTML provides dynamic styles by which the appearance and styles of elements can be changed dynamically.
- Fonts, color, style, the content of web pages can be changes using DHTML.
