Styles and themes

Styles are useful for defining the look and feel of your applications built with Adobe® Flex®. You can use them to change the appearance of a single component, or apply them across all components.

The emphasis on using style properties in Flex 4 has been reduced. Instead of styling individual components, or classes of components, you can use custom skins to perform most operations that change the look and feel of your applications. This includes adding background colors and images, borders, and other properties that were styleable in Flex 3 applications.
