Flex supports external CSS style sheets. You can declare the location of a local style sheet or use the external style sheet to define the styles that all applications use. To apply a style sheet to the current document and its child documents, use the source property of the <mx:Style> tag.
The following example points to the style.css file in the flex_app_root/assets directory:
<?xml version="1.0"?>
<!-- styles/ExternalCSSExample.mxml -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Style source="../assets/style.css"/>
<mx:Button id="myButton" label="Click Here"/>
</mx:Application>

A common hurdle a developer may face is dealing with exceptions in BlazeDS. When an exception is thrown in Java, how do we handle this in flex? Here is a simple and flexible approach inspired by Scott Morgan.
1. Create a Java Class that extends RuntimeException.
package com.flexpasta.exception;
public class FlexException extends RuntimeException
{
public FlexException(String message)
{
super(message);
}
}

Understanding Frameworks
It is important to understand what a framework is before you start using one for the first time.
The word “framework” is often misunderstood in the software development field. There are two different types of frameworks, one being application frameworks and the other being architectural frameworks.
For a more in-depth explanation of frameworks, refer to part 1 of Steven Webster’s series of articles at http://www.adobe.com/devnet/flex/articles/cairngorm_pt1_02.html.
