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.
