# Interface CSSValueList

All Superinterfaces:
  `CSSValue`

public interface CSSValueList extends CSSValue
The `CSSValueList` interface provides the abstraction of an ordered collection of CSS values.

Some properties allow an empty list into 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.

See also the Document Object Model (DOM) Level 2 Style Specification.

Since:
  1.4, DOM Level 2
