Example
The ButtonAppearance related properties allows to configure appearance of button for a particular state. That allows to configure colors, borders, images, fonts, etc. If a property for a particular state is not set, then the corresponding property of the appearance for the normal state of button is used automatically. If the UseBrowserDefaults is enabled and the appearances are not set, then the defaults for a particular browser are used automatically.
