CSS

The appearance of Apps is controlled by CSS. All objects have a default appearance, and supplied Apps will include CSS that you can modify. In addition, all controls have an optional CSS Class property. If you set this to a class that you have added to the CSS, it overrides the default CSS for that specific control. See the CSS topics for the primary content on CSS.

The Scripting area includes CSS Editor. See Scripting for details on this aspect of Designer.
