CSSStyleDeclaration: getPropertyCSSValue() method

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 CSSStyleDeclaration.getPropertyCSSValue() method interface returns a CSSValue containing the CSS value for a property. Note that it returns null if the property name is a shorthand 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:

CSSStyleDeclaration.getPropertyValue() of the untyped CSS Object Model, widely supported, or
Element.computedStyleMap() of the modern CSS Typed Object Model API, less supported and considered experimental.

Syntax

getPropertyCSSValue(property)

Parameters

property: A string representing the property name to be retrieved.

Return value

A CSSValue containing the CSS value for a property. If none exists, returns null.

Examples

The following JavaScript code gets an object containing the computed RGB values of the color CSS property:

const style = window.getComputedStyle(elem, null);
const rgbObj = style.getPropertyCSSValue("color").getRGBColorValue();

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It has been superseded by a modern, but incompatible, CSS Typed Object Model API that is now on the standard track.
