Using user style sheet to modify the style of a web site

I tried to modify the style by using user style sheet. But some of style just could not take effect. I seemingly forget the basic rule of css cascade. The cascade works in the following order of importance:

Function.createDelegate

function greet(message) {
        alert(message + ", " + this.name);
    }

Function.createCallback

   var createCallback = function(method, context) {
    return function() {
        //the arguements is passed in when the this callback
        //method is call
        //if there is parameter passed
        //package the parameter with the context
        //into an array, an invoke the callback
        //method with the array
        var l = arguments.length;
        if (l > 0) {
            var args = [];
            for (var i = 0; i < l; i++) {
                args[i] = arguments[i];
            }
            //the last array member is the 
            //the context
            args[l] = context;
