You use Adobe Flex Builder to create behaviors that add animation and motion to a component in response to user or programmatic action. For example, you can create a behavior for a TextInput component that causes it to bounce slightly when the user tabs to it, or you can create a behavior for a Label component that causes it to fade out when the user passes the mouse over it.

This topic describes how to visually create behaviors for components. For information on creating behaviors in MXML and ActionScript code, see Using Behaviors in the Adobe Flex 3 Developer Guide.
