SAS applications are displayed with the Flex interface that is provided by a particular
version of SAS Application Themes for Flex. At start-up time, Flex applications load
Flex themes automatically. A
theme consists of SWF files that include cascading style sheets (CSS) files. The theme
content is downloaded to the client, and is cached by the user's web browser. As a
result, during subsequent uses of the web application, the theme content loads quicker
than when it is initially loaded. The SAS Corporate theme is the default theme for
SAS applications that use Flex themes.
