html - How can I use HTML5 in all browsers including IE7,8?

Question

I want to use HTML5 because it supports in Iphone also and I really liked its capabilities but what can I do if it is not fully compatible with all browsers? Specially IE family. So is there a way by adding some js script e.t.c. so that HTML5 and its js api work normally in IE also as it works on other browsers like chrome, firefox and opera e.t.c.? So that I can use it without thinking of browser compatibility issues. There are also many game engines in html5 but what if this is not supported major IE browsers. Or can some one tell that how much advantage can I take of html5 without thinking of compatibility issues?

Thanks in advance

You can use http://html5boilerplate.com/ together with http://code.google.com/p/html5shiv/ and you're good to go.

For some other cool features, like video in old IE, you need to use workarounds like Flash for video and Javascript libs for canvas.
