因为本人对html 5中的新标签不是很熟悉，现在已经用html 4写好了页面代码，可是老板要求加入大量视频，说在html 5中很方便，现在就想问问，在html 4中写的代码，直接复制粘贴过去在html 5中能用吗?
如果不能用，有没有什么技巧可以解决这个问题，可以不用重写一遍代码，毕竟html 5在浏览器中还有很多的兼容问题，本人还是一只前端的菜鸟，望各位大神帮忙解决，不胜感激涕零

html5 vedio可以直接加入视频不用flash 很方便兼容性也很好

那有哪些特殊的属性和标签呢

可以用 html5增加了视频和canvas一些标签

那么可以通过添加超链接来加入视频吗

可以直接复制过去但是有些新特效需要改一下，比如说单标签需要再加个斜杠
