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.
