Detailed Description

The CSSPrimitiveValue interface represents a single CSS value . This interface may be used to determine the value of a specific style property currently set in a block or to set a specific style properties explicitly within the block. An instance of this interface can be obtained from the getPropertyCSSValue method of the CSSStyleDeclaration interface.
