CSSValue

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 CSSValue interface 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 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.

Instance properties

CSSValue.cssText

A string representing the current value.

CSSValue.cssValueType Read only

An unsigned short representing a code defining the type of the value. Possible values are:

Constant	Description
`CSS_CUSTOM`	The value is a custom value.
`CSS_INHERIT`	The value is inherited and the `cssText` contains `"inherit"`.
`CSS_PRIMITIVE_VALUE`	The value is a primitive value and an instance of the `CSSPrimitiveValue` interface can be obtained by using binding-specific casting methods on this instance of the `CSSValue` interface.
`CSS_VALUE_LIST`	The value is a `CSSValue` list and an instance of the `CSSValueList` interface can be obtained by using binding-specific casting methods on this instance of the `CSSValue` interface.

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It has been superseded by a modern, but incompatible, CSS Typed Object Model API that is now on the standard track.
