The AddToCartButtonCssClass property is used to set the style sheet class used to control the format of the Add To Cart button in the ShoppingCartQuickEntryControl. The class specified in the property can also be used to apply formatting to the text specified by the AddToCartButtonText property through class inheritance.
The value set in the property must correlate to a CSS class that is available to the CyberStore page that contains the control, and is either within a loaded .css file, or the HTML of a theme or custom control.
