		HTML: 负责网页的结构	
		CSS： 负责网页的样式（美观）
		Javascript： 负责在浏览器端与用户进行交互。

		负责静态的网页制作的语言
			
		HTML语言特点：
				1）由标签组成。 <title> <p> <hr/> <br/>
				2）语法结构松散的    <p></p>   <p>  <P> 
					大小写不区分
					结束标签和开始标签不一定匹配

<html>
	<head>
		<title>this is title</title>
	</head>
	<body>
		<p>html标签</p>
		<P>html标签</P>
		<abc>abc标签</abc>  自定义标签
	</body>
</html>
