this last nStyle.appendChild(cssText); returns the following error in IE6:
Error: Unexpected call to method or property access.

Known problem with IE, IE 4 started with its own object model and while
IE 5 and later are supposed to implement the W3C DOM unfortunately there
are some elements on which full core DOM support is not there so that
for instance appendChild does not work, script and style elements are
examples of that. It is mostly elements where IE already has/had its own
specialized API to construct the contents of the element, for instance
the contents of the style element is a (CSS) stylesheet and IE has its
own API to add rules to such a sheet.
So some way to add a style rule with IE/Win and with Mozilla and with
Opera 8 is
var style = document.createElement('style');
style.type = 'text/css';
var selector = 'html';
var properties = 'color: darkblue; background-color: lightblue';
document.getElementsByTagName('head').item(0).appe ndChild(style);
if (document.styleSheets) {
var lastSheet = document.styleSheets[document.styleSheets.length - 1];
if (lastSheet && typeof lastSheet.addRule != 'undefined') {
lastSheet.addRule(selector, properties);
}
else {
style.appendChild(document.createTextNode(selector + ' { ' +
properties + ' }'));
}
}
else {
style.appendChild(document.createTextNode(selector + ' { ' +
properties + ' }'));
}
Or you could use try/catch to catch the IE error and then script the IE way.
