Hello. Please, help me.

I want format all textfields of my flash-app with single css;

I've already written this function:
Code:
function formatWithCss(field, xml_html) {
    field.html = true;
    field.wordWrap = true;
    field.multiline = true;
    field.condenseWhite = true;
    
    var css = new TextField.StyleSheet();
    css.onLoad = function(success) {
       field.styleSheet = css;
       field.htmlText = xml_html;
    };
    css.load('styles.css');
}
Big disadvantage of this approach is that my app opens styles.css for each textfield.
How can I read styles.css once and use it many times?
