我正在查看HTML5支持的维基页面，让它感到有些困惑。 这是链接
如果我理解它，那么IE几乎没有支持，而其他人则介于一点点和一点点之间。 没有很多。
因此，HTML 5包含了大量不同的技术，有些技术比其他技术更接近完成。 那么让我们专注于说Canvas和拖放以及你认为有意义的任何其他东西，视频标签？ 你选。
我也不确定Javascript中有什么变化。 我假设有一些新的API用于Canvas这样的东西？
如果我只使用HTML5，特别是有趣的东西，Canvas等，那么很大一部分网络用户都无法使用我的网站吗？
I was looking at a wiki page on HTML5 support and left it feeling a little confused. Here's the link
If I understand it, then IE has near to no support and the others have between a little and some. none have lots.
So HTML 5 incorporates a load of different technologies, some closer to completion than others. So let's focus on say Canvas and drag and drop and anything else you think would make sense, Video tag? You choose.
I'm also not sure what has changed in Javascript. I assume there are new APIs for things like Canvas?
Would a significant segment of web users be unable to use my site if I only used HTML5, especially the fun stuff, Canvas, etc?

所有当前浏览器都支持HTML5。 它支持HTML5的程度和程度有多大，因此其他人发布了有用的链接。 但是，您需要小心谨慎，因为浏览器可能会声称支持，但这样做很差或不完整。 <audio如果要使用preload属性，则在每个浏览器中都可以正常运行，但IE可以运行。 'contenteditable'属性很棒但是，如果用户点击返回键，则会得到不同的结果。
简单的例子，但要考虑的事情。 最终它将全部解决。
无论如何，我们尽可能使用HTML5技术，因为最终每个人都会。 他们非常有帮助。
All current browsers support HTML5. Just how much and how well it supports HTML5 is in question, hence the helpful links others have posted. However you need to be cautious because a browser may claim support but does so poorly or incompletely. <audio works great in every browser but IE if you want to use the preload attribute. The 'contenteditable' attribute is wonderful but, if the user hits the return key, you get different results.
Simple examples but something to think about. Eventually it will all sort out.
In any case, we use HTML5 technologies wherever we can because eventually everyone will. They're very helpful.
