Interface CSSValueList
- CSSValue
public interface CSSValueList
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.
