Loading CSS Styleheet in IE8, E7, and IE6 Dynamically

Since innerHTML doesn't work in IE8 and below. Here is a hack for inserting CSS Styleheet in IE8 using javascript programmatically.

  var css = 'body {color:red}';
  var style = document.createElement('style');
  style.setAttribute("type", "text/css");
  var head = document.getElementsByTagName('head')[0];
  head.appendChild(style);
  if (style.styleSheet) {   // IE
    style.styleSheet.cssText = css;

  } else {  // modern browser
    var node = document.createTextNode(css);
    style.appendChild(node);
  }
