IE8 beta 2 supports two APIs from HTML5: <a href="http://www.whatwg.org/specs/web-apps/current-work/#crossDocumentMessages" rel="noreferrer">cross-document messaging</a> and <a href="http://www.whatwg.org/specs/web-apps/current-work/#storage" rel="noreferrer">non-SQL storage</a>.

IE8 beta 2 doesn’t implement the HTML5 parsing algorithm or the new elements (no <code>&lt;canvas&gt;</code> or <code>&lt;video&gt;</code> support).

There are also bug fixes that align IE8 better with HTML5.

blocks|key|1474886|text|您可以通过在头部中包含此JavaScript来使HTML5标记在IE8中工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1474887|<script+type="text/javascript">

You can get HTML5 tags working in IE8 by including this JavaScript in the head.

<pre><code>&lt;script type="text/javascript"&gt;
 document.createElement('header');
 document.createElement('nav');
 document.createElement('menu');
 document.createElement('section');
 document.createElement('article');
 document.createElement('aside');
 document.createElement('footer');
&lt;/script&gt;
</code></pre>

blocks|key|1689630|text|您可以使用this+IE+HTML5+shim+script为HTML5中的新语义元素(如<article>+)获得基本级别的支持。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1689631|entityMap|0|LINK|mutability|MUTABLE|url|http://remysharp.com/2009/01/07/html5-enabling-script/^0|19|9|5|P|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@$9|O|A|P|B|C]]|D|@$9|Q|A|R|1|S]]|E|$]]|$1|F|3|-4|5|6|7|T|8|@]|D|@]|E|$]]]|G|$H|$5|I|J|K|E|$L|M]]]]

You can use <a href="http://remysharp.com/2009/01/07/html5-enabling-script/" rel="noreferrer">this IE HTML5 shim script</a> to gain a basic level of support for the new semantic elements in HTML5 such as <code>&lt;article&gt;</code>.

blocks|key|1474663|text|对于提供IE+HTML5渲染功能，Modernizr也是一个很好的选择。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1474664|entityMap|0|LINK|mutability|MUTABLE|url|http://www.modernizr.com/^0|H|9|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

<a href="http://www.modernizr.com/" rel="noreferrer">Modernizr</a> is also a great option for giving IE HTML5 rendering capabilities.

Does it support 

<pre><code>&lt;!DOCTYPE html&gt;
</code></pre>

Yes it does.

Perhaps a better question is what modern web features IE8 supports. Some of the best places to answer that are <a href="http://caniuse.com/" rel="noreferrer">caniuse.com</a>, <a href="http://html5test.com/" rel="noreferrer">html5test.com</a>, and <a href="http://browserscope.org" rel="noreferrer">browserscope.org</a>.

HTML5 means a lot of different things to different people. These days, it means HTML, CSS, and JavaScript functionality. The term is becoming a bit "Web 2.0"-like.

Also are supported HTML5 <a href="http://www.whatwg.org/specs/web-apps/current-work/#handler-onhashchange" rel="noreferrer">hashchange event</a> and <a href="http://www.whatwg.org/specs/web-apps/current-work/#dom-navigator-online" rel="noreferrer">ononline, offline event</a>

blocks|key|1689850|text|HTML5仍处于规范草案中(并将持续很长一段时间)。为什么要麻烦呢？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1689851|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

HTML5 is still in draft spec (and will be for a loooong time). Why bother?

blocks|key|1475167|text|您可以使用它来使IE8理解/支持基本的HTML5标记。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1475168||code-block|syntax|javascript|1475169|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

You can use this to make IE8 understand/support basic HTML5 tags.

<pre><code>&lt;!--[if lt IE 9 ]&gt; 
 &lt;script type="text/javascript"&gt;
 var html5Elem = ['header', 'nav', 'menu', 'section', 'article', 'aside', 'footer'];
 for (var i = 0; i &lt; html5Elem.length; i++){
 document.createElement(html5Elem[i]);
 }
 &lt;/script&gt;
&lt;![endif]--&gt;
</code></pre>

blocks|key|1474402|text|根据http://msdn.microsoft.com/en-us/library/cc288472(VS.85).aspx#html的说法，IE8将会有“强大的”HTML5支持。我还没有看到任何讨论“强有力的支持”到底需要什么的东西，但我可以说，是的，一些HTML5的东西将进入IE8。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1474403|entityMap|0|LINK|mutability|MUTABLE|url|http://msdn.microsoft.com/en-us/library/cc288472(VS.85).aspx#html)^0|2|1T|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

According to <a href="http://msdn.microsoft.com/en-us/library/cc288472(VS.85).aspx#html" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/cc288472(VS.85).aspx#html</a>, IE8 will have "strong" HTML 5 support. I haven't seen anything discussing exactly what "strong support" entails, but I can say that yes, some HTML5 stuff is going to make it into IE8.
