Apply CSS Rules to IE only
There are 2 ways to do so. One like below
<!--[if IE]>
<style type="text/css">
IE specific CSS rules go here
</style>
<![endif]-->
And second one like to avoid loading multiple CSS files or to have inline CSS is to hand a class to the body tag depending on the version of Internet Explorer.
<!--[if IE ]><body class="ie"><![endif]-->
<!--[if !IE]>--><body><!--<![endif]-->
Now in your css code, you can simply do:
.ie .abc {
position:absolute;
left:30;
top:-10;
}
