I can't get my style sheets to apply to my popup window. I'm probably misses something simple but I can't seem to figure out what. I use the CSS on other pages with the same link and it works fine.
CSS
.Code128 {
    font-size: 50px;
}
JQuery
$(document).ready(function () {
    $('#Print').on("click", function () {
        Popup($('#PrintDiv').html());
    });
    function Popup(data) {
        var mywindow = window.open('', 'Print Label', 'height=400,width=600');
        mywindow.document.write('<html><head><title>Print Label</title>');
        mywindow.document.write('<link rel="stylesheet" type="text/css" href="~/Content/Fonts.css"/>');
        mywindow.document.write('<link rel="stylesheet" type="text/css" href="~/Content/Label.css"/>');
        mywindow.document.write('</head><body >');
        mywindow.document.write(data);
        mywindow.document.write('</body></html>');
       // mywindow.print();
       // mywindow.close();
    }
});
HTML
<div id="PrintDiv">
    <div class="Code128">BarCode</div>
    <div class="Code128">Bar Code</div>
</div>
