# Ext.Shadow

Simple class that can provide a shadow effect for any element. Note that the element MUST be absolutely positioned, and the shadow does not provide any shimming. This should be used only in simple cases -- for more advanced functionality that can also provide the same shadow effect, see the Ext.Layer class.
