CSSValue
public interface CSSPrimitiveValue extends CSSValue
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. Conversions are allowed between absolute values (from millimeters to centimeters, from degrees to radians, and so on) but not between relative values. (For example, a pixel value cannot be converted to a centimeter value.) Percentage values can't be converted since they are relative to the parent value (or another property value). There is one exception for color percentage values: since a color percentage value is relative to the range 0-255, a color percentage value can be converted to a number; (see also the RGBColor
interface).
