The CSSValueList interface derives from the CSSValue interface and provides the abstraction of an ordered collection of CSS values.
Some properties allow an empty list in their syntax. In that case, these properties take the none identifier. So, an empty list means that the property has the value none.
The items in the CSSValueList are accessible via an integral index, starting from 0.
