Dynamic Hypertext Markup Language

Dynamic HTML, or DHTML, is a collection of web technologies used together to create interactive and animated web sites by using a combination of a static markup language (such as HTML, XHTML), a client-side scripting language (such as JavaScript), a presentation definition language (such as CSS), and the Document Object Model.

Static Websites

HTML and CSS can create a static website only. A Static website means a website with fixed contents, where we cannot interact with the user, we cannot send form inputs to the server, we cannot create image sliders, and tabs etc.

A static website code


<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>Static Webpage</title>
<style>
*{
	margin:0px;
	padding:0px;
}
.wrap{
	width:960px;             
	height:auto;
	border:1px solid red;
}
.header{
	height:150px;
	background:#333;
}
.nav{
	height:50px;
	background:#000;
}
.container{
	background:#ccc;
}
.left{
	width:30%;
	height:200px;
	float:left;
	background:#333;
}
.right{
	width:70%;
	height:200px;
	float:left;
}
.clear{
	clear:both;    // Clear Both will clear floating from both sides.
