Javascript

var ie = (function(){



    var undef,

        v = 3,

        div = document.createElement('div'),

        all = div.getElementsByTagName('i');



    while (

        div.innerHTML = '<!--[if gt IE ' + (++v) + ']><i></i><![endif]-->',

        all[0]

    );



    return v > 4 ? v : undef;



}());

You can then do:

ie < 9
