Designing Look and Feel with the Flex 2 Style Explorer
The Flex Builder is a great IDE for rapidly developing and designing applications. It also comes with its own tools for quickly stylizing components. However, like all things, there's a good approach, and a bad approach. When stylizing through Flex Builder's design mode, you are actually applying the styles to the application's mxml tags directly. This makes it difficult to reuse and update styles effectively.
Just like with HTML, the best approach is to use CSS, and, fortunately, Adobe has been so gracious as to offer the same opportunity for styling in Flex. We don't get nearly as much visual leverage when working with CSS, however, since Flex Builder offers no special tools for generating them. This is where the Adobe consulting team comes to the rescue, with a powerful CSS generator tool called the Flex 2 Style Explorer.
