CSSPrimitiveValue class

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 property explicitly within the block. An instance of this interface might be obtained from the getPropertyCSSValue method of the CSSStyleDeclaration interface. A CSSPrimitiveValue object only occurs in a context of a CSS property.

Inheritance: CSSPrimitiveValue → CSSValue → DOMObject

The CSSPrimitiveValue type exposes the following members:
