DHTML? What is it?

[GMailGuy]

Well I have heard a lot about DHTML.. what exactly is it? I know it id Dynamic Hypertext markup language (or something similar) but what has it different from HTML and when should it be used?

I'm no expert on the subject, but it seems like a fusion between HTML and JavaScript. I'm not sure when it should be used, because in my short four years of web development, I've never used it. If I needed something "dynamic" I used JavaScript and PHP, now I take advantage of the new AJAX technology.

Hi GMailGuy!

As you know HTML is a markup language. You can use it to create webpages. You can format texts, use images, links and so on. By the way nowadays the proposed formatting technique is CSS. There are many HTML versions (for example 2.0, 3.2, 4.0 és a 4.01).
---
The newest version is XHTML. It is based on the "classic" HTML, but it has more strict rules. So when we want to create a XHTML page we have to follow the XML rules as well. For example all tags must be terminated.
---
In a DHTML page you can use many dynamic content generator devices, for example JavaScript. You can create many interesting effects (with JS and CSS).

I think thats all in a nutshell.

Just a DHTML have an extension on the end, such as .dhtml? I don't think XHTML has that, at least I've never seen it.

No, they still have the same .html extension, the code is different.
