TheCSSValueList interface derives from theCSSValue interface and provides the abstraction of an ordered collection of CSS values.

Note:This interface was part of an attempt to create a typed CSS Object Model. This attempt has been abandoned, and most browsers donot implement it.

To achieve your purpose, you can use:

the untypedCSS Object Model, widely supported, or
the modernCSS Typed Object Model API, less supported and considered experimental.

Some properties allow an empty list in their syntax. In that case, these properties take thenone identifier. So, an empty list means that the property has the valuenone.

The items in theCSSValueList are accessible via an integral index, starting from 0.
