So I have been working on a site (http://getcours.tk/), recently, It works fine in Chrome (So webkit) and Firefox (So Gecko) but I just tried it out in Internet explorer 8 and Since it doesn't seem to follow CSS3 standards, It is incapable of rendering it properly.
I just want to display a message to users of internet explorer 8 and below (ie9 works) to say that the site will display incorrectly in their browser, and that if they wish to see it properly they should Use a Modern browser.
Really hoping for a hand here, thanks to anyone who can help

It's really simple actually. You can paste this anywhere in your page and everything inside it will only be rendered by IE8 and below
<!--[if lt IE 8]>
//Whatever you want here
//For example, specific css only for IE
<link rel="stylesheet" type="text/css" href="cssIE.css" />
<![endif]-->
Similarily you can use "gt" (greater than) instead of "lt" or any number version you want.
