Interface CSSValueList
- 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.

Model (DOM) Level 2 Style Specification.
