package ch12_1
{
	import flash.display.MovieClip;
	import flash.text.StyleSheet;
	import flash.text.TextField;
	
	public class CSSText extends MovieClip
	{
		public function CSSText()
		{
			//声明说明对象
		 var st:Object = new Object();
		 st.fontSize ="24";
		 st.fontWeight ="bold";
		 st.fontStyle ="italic";
		 st.color ="#FF0000";
		 
		 
		 //使用st方法将该对象添加到样式表对象中
		 var style:StyleSheet = new StyleSheet();
		 style.setStyle(".title",st);
		 
		 //设置文本的样式属性
		 var tf:TextField = new TextField();
		 tf.styleSheet =style;
		 
		 tf.htmlText ="<span class ='title'>007</span>你好吗？";
		 addChild(tf);
		}
