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
