Many of time you 
have seen that few tags are not supported by Internet Explorer. Even I have used 
<aside> tag that is not compatible with Internet Explorer 8 see my article <aside> tag. There you will see that Internet Explorer 8 not 
give proper output that is way, I used Internet Explorer 9 to represent how 
aside tag work on Internet Explorer 9.
The <script> tag is very useful to define client side script but in this code I 
used it for only to make my Internet Explorer compatible to represent my aside 
tag.
Code: 
<!DOCTYPE
HTML >
<html>
<head>
    <script
type="text/javascript">
         document.createElement("aside");
    </script>
    <title></title>
</head>
<body>
        <aside

             Working With Area Tag in HTML5</h1>
        <p>
            The 
area tag is used only within a map tag. The area tag is used to define the areas
	    on 
the image map that whenever the user clicks on the area the other page that the
             user is navigated to. The image map is used to divide the image into clickable 
areas
            and 
the clickable areas work like a hyperlink.

<h1>
    HyperText 
Markup Language</h1>
<b>HTML5</b> 
is a language for structuring and presenting content for the World Wide Web, a 
core technology
of the Internet. 
It is the fifth revision of the HTML standard (originally created in 1990 and 
most recently
standardized as 
HTML4 in 1997) and as of June 2011[update] was still under development. Its core 
aims have been to improve the language with support for the latest multimedia 
while keeping it easily readable by humans and consistently understood by 
computers and devices (web browsers,parsers etc.). HTML5 is intended to subsume 
not only HTML4, but XHTML1 and DOM2HTML (particularly JavaScript) as well.

In the above code, I have applied <script> tag only on aside tag. You can apply 
script on many tag see below code. There are two way to apply script on all 
tags.
First code
<script
type="text/javascript">
     document.createElement('header');
     document.createElement('hgroup');
     document.createElement('nav');
     document.createElement('menu');
     document.createElement('section');
     document.createElement('article');
     document.createElement('aside');
     document.createElement('footer');
</script>
Second code
<!--[if IE]>
<script type="text/javascript">
var html5elements =
"abbr,article,aside,audio,canvas,datalist,details,figure,footer,header,hgroup,mark,menu,meter,nav,output,progress,section,time,video".split(',');
for (var i = 0; i < html5elements.length; i++)
document.createElement(html5elements[i]);
</script>
<![endif]-->
