CSSUnparsedValue: CSSUnparsedValue() constructor

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The CSSUnparsedValue() constructor creates a new CSSUnparsedValue object which represents property values that reference custom properties.

Syntax

js
new CSSUnparsedValue(members)

Parameters

members

An array whose values must be either a string or a CSSVariableReferenceValue.

Examples

js
const value = new CSSUnparsedValue(["4deg"]);
const values = new CSSUnparsedValue(["1em", "#445566", "-45px"]);

console.log(value); // CSSUnparsedValue {0: "4deg", length: 1}
console.log(values); // CSSUnparsedValue {0: "1em", 1: "#445566", 2: "-45px", length: 3}
