I need help applying CSS in AS3

Hello,

I have Googled this all afternoon. How do you apply a style in AS3? I need to apply them to movieclips and hopefully a textArea.

Thanks for the look.

The CSS


swfStyle{
font-family: Arial;
font-size: 12px;
text-align:center;
color:#FF0000;
}

The AS3


/********* Load the CSS file.******************************/
var loadCSSFile:String = "styles/new_pup.css";// Get the URL for the HTML file
var loadedCSSFile:String;// Variable to store the HTML data
var loader2:URLLoader = new URLLoader();
loader2.addEventListener(Event.COMPLETE, handleCSSLoad);
loader2.addEventListener(IOErrorEvent.IO_ERROR, onIOError, false, 0, true);
loader2.load(new URLRequest(loadCSSFile));

function handleCSSLoad(evt:Event):void
{
	//mcPopup.txtContent.htmlText = "In the handleCSSLoad function";
	
	loader2.removeEventListener(Event.COMPLETE, handleCSSLoad);
	var cssStyle:StyleSheet = new StyleSheet();
	cssStyle.parseCSS(evt.target.data);
	//txtTitle.styleSheet = cssStyle;
	//mcPopup.txtContent.styleSheet = cssStyle;
	style = cssStyle.getStyle("swfStyle");
		
	loader.load(new URLRequest(loadHTMLFile));
}
