第二回合:HTML5的新特性

与之前的HTML4.01相比,HTML5增加了非常多的改变:

新的语义元素

新的元素特性:增加新的元素属性、表单元素、验证功能等内容。

多媒体:增加

2D/3D 绘图:增加 绘图元素。

存储:增加在线、离线存储功能。

连通性:增加客户端与服务器交互的两个内容:Web Sockets(客户端与服务器持久连接)和Server-sent events(服务器推送数据)等。

集成:提供Web Workers、History API、requestAnimationFrame、地理位置等强大的功能。

设备访问:提供对摄像头、移动设备的支持。

CSS3样式:提供了新的背景样式特性、动画、边框等样式。

下面我们用实例来说明下各个标签的使用以及h5与c3的配合。

html代码如下:

DOCTYPE html> html> head> meta charset="utf-8" /> title>HTML5title> link rel="stylesheet" href="html5.css"> head> body> header class="show"> h1>Headerh1> h2>Subtitleh2> header> div id="container"> nav> h3>Navh3> a href="">HTML5a> a href="">CSS3a> a href="">Javascripta> nav> section> article> header> h1>Article Headerh1> header> p>Lorem ipsum dolor HTML5 nunc aut nunquam sit amet, consectetur adipiscing elit.

css代码如下:
