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
