CSSPrimitiveValue

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see thecompatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

TheCSSPrimitiveValue interface derives from theCSSValue interface and represents the current computed value of a CSS property.

Note:This interface was part of an attempt to create a typed CSS Object Model. This attempt has been abandoned, and most browsers donot implement it.

To achieve your purpose, you can use:

the untypedCSS Object Model, widely supported, or
the modernCSS Typed Object Model API, less supported and considered experimental.

This interface represents a single CSS value. It 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 thegetPropertyCSSValue() method of theCSSStyleDeclaration interface. ACSSPrimitiveValue 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 theRGBColor interface).
