HTML5中的视频标签和及其模仿视频播放器的效果在一些手机端应用比较多。因为手机端基本上废除了flash的独断，让HTML5当家做主人，所以对视频支持的比较好。所以今天专门为大家奉上HTML5视频标签模拟视频播放器的小例子，让大家更好的理解HTML5和有效的应用在项目中。

　　HTML代码

<!-- src中放上本地的ogv的音频 -->
<video id="v1" src="Intermission-Walk-in.ogv"></video>
<div id="div1">
	<input type="button" value="播放" />
	<input type="button" value="00:00:00" />
	<input type="button" value="00:00:00" />
	<input type="button" value="静音" />
	<input type="button" value="全屏" />
</div>
<div id="div2">
	<div id="div3"></div>
</div>

<div id="div4">
	<div id="div5"></div>
</div>

　　CSS代码

#div2{ width:300px; height:30px; background:#666666; position:relative;}
#div3{ width:30px; height:30px; background:red; position:absolute; left:0; top:0;}
#div4{ width:300px; height:20px; background:#666666; position:relative; top:10px;}
#div5{ width:20px; height:20px; background:yellow; position:absolute; right:0; top:0;}
