CSSValue

View on MDN ↗

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:

Instance properties

  • cssText Deprecated
    • : A string representing the current value.
  • cssValueType Read only Deprecated
    • : An unsigned short representing a code defining the type of the value. Possible values are:

      ConstantDescription
      CSS_CUSTOMThe value is a custom value.
      CSS_INHERITThe value is inherited and the cssText contains "inherit".
      CSS_PRIMITIVE_VALUEThe 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_LISTThe 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It has been superseded by a modern, but incompatible, CSS Typed Object Model API that is now on the standard track.
