Try to use selectivizr. But I don't understant how it works..
<script src="jquery-1.11.2.js"></script>
<!--[if (gte IE 6)&(lte IE 8)]>
<script type="text/javascript" src="selectivizr.js"></script>
<noscript>
<link rel="stylesheet" href="css/styleie.css" />
</noscript>
<![endif]-->
This how I connect it:
.button input[type="radio"] {
display: none;
}
input[type="radio"]:checked + label {
border: 1px solid red;
}
style.css in styleie.css same code.
Testing on IE 11 in f12 mode ( IE8 capability)
