A good way 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 you only need general IE hacks, you can do something like this, but it can be extended to be version specific:
<!--[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;
}
This also keeps your CSS files valid, as you do not have to use dirty (and invalid) CSS hacks.
