backgroundPosition background-position	String	Sets the position of the background when the background-repeat value is no-repeat. Default Value: '50% 50%'
backgroundRepeat background-repeat	Boolean, String	Sets the repeating mode for the background image. Default Value: 'repeat'
backgroundScale background-scale	Number	Scales the background image using the specified ratio. Default Value: 1
border	Number	Sets the border width of the object. Can be a single value or a string of values, setting the values in the order "top right bottom left"
borderAlpha border-alpha	Number	Sets the transparency level of the border on the object. Values must range between 0.0 and 1.0, with 0.0 being completely transparent and 1.0 being completely opaque.
