In this Flash ActionScript 3.0 tutorial you can learn how to load an external CSS style sheet to allow a dynamic text field in flash to be affected by it. A few code considerations must be met which enable the text field to properly render the CSS styles you set in the external file,and we address them in the video. There are several ways you can go about using CSS in your flash text fields... use an external file like we did in this example... set the styles directly in ActionScript and do away with the need for an external CSS file... but you can choose the method that is right for you.
