About Dynamtic HTML
DHTML, or Dynamtic HTML, is a word that is used to describe a group of technological tools that are used to make web sites more interactive. In addition to interactivity, the use of animation plays an important role with DHTML as well. It should be noted that DHTML is comprised of both HTML and scripting languages such as JavaScript. However, it is also composed of things such as the Document Object Model and CSS as well. While DHTML has a number of powerful features, its inability to work well on multiple platforms has caused it to fall out of favor in recent years, and more developers are using tools such as Ajax instead.
DHTML is a system that is challenging to use. This is especially true when it comes to debugging. It has different levels of support for the many web browsers available today, and the size of the screen may have to be adjusted to work correct with browsers such as Netscape or Opera. It is important to realize that DHTML is not a single technology, but a collection of various technologies that work together seamlessly. Many people make the mistake of confusing DHTML with systems such as PHP, but they are different. The primary purpose of DHTML is to create changes in the appearance of a webpage by using things such as JavaScript or CSS. This will give the web page a "dynamic" appearance instead of the "static" appearance.
More importantly, the effect that DHTML has on a page will only be evident once the page has been fully loaded. The effects attributed to DHTML are dependent on the way it behaves on the web page that the user is viewing. The primary difference between DHTML and PHP is that DHTML does not place an emphasis on making sure the information loaded on the page is unique. When DHTML code is generated, it will often be placed inside an external file. This can be achieved by connecting the file to the file that holds the JavaScript. This is very important when multiple pages utilize an identical script. Functions are also heavily used in DHTML. A webpage can be designed so that a large part of the page can be showcased to users who ask for it. This is quite useful in educational websites.
DHTML is a powerful tool because it is an extension of HTML, the older system that created the foundation for the Internet. While HTML is static, DHTML is dynamic. This is the primary difference between the two. The advent of DHTML allowed the Internet to become more interactive. Users could view a dynamic page instead of one that simply sits still, never changing. The process of creating DHTML was complex, and involved the contribution of a number of different technologies. The ultimate goal of technologies such as DHTML is to give the user more control over the information they view on websites. However, DHTML was not designed to deal with altering the information on each page that was loaded. This was the domain of other technologies.
