The Theme for Web object helps you to define the look and feel of your Web application.
Every Knowledge Base contains a Theme for Web object named 'Carmine' automatically created and it is used by default when generating Web applications.
The 'Carmine' Theme is referenced in the Default Theme property at version level.
Besides, every Web Panel object and Transaction object contains the Theme property (which by default inherits the Theme configured in the Default Theme property).
Of course, you are able to change the values of all these properties by other Themes for Web defined in your KB.
