CSSPrimitiveValue.primitiveType

The primitiveType read-only property of the CSSPrimitiveValue interface represents the type of a CSS value.

Note: This property was part of an attempt to create a typed CSS Object Model. This attempt has been abandoned, and most browsers do not implement it.

To achieve your purpose, you can use:

Syntax

type = cssPrimitiveValue.primitiveType;

Specifications

This feature was originally defined in the DOM Style Level 2 specification, but has been dropped from any standardization effort since then.

It has been superseded by a modern, but incompatible, CSS Typed Object Model API that is now on the standard track.
