CSSPrimitiveValue: primitiveType property
=========================================

**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 the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

 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:

* the untyped CSS Object Model, widely supported, or
* the modern CSS Typed Object Model API, less supported and considered experimental.

const cssValue = cs.getPropertyCSSValue("color");
console.log(cssValue.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It has been superseded by a modern, but incompatible, CSS Typed Object Model API that is now on the standard track.
