The CSSValueList interface derives from the CSSValue interface and provides the abstraction of an ordered collection of CSS values.

Some properties allow an empty list in 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.

Properties

Inherits properties from its parent, CSSValue.

CSSValueList.lengthRead only
An unsigned long representing the number of CSSValues in the list.

Methods

CSSValueList.item()
This method is used to retrieve a CSSValue by ordinal index. The order in this collection represents the order of the values in the CSS style property. If index is greater than or equal to the number of values in the list, this returns null.
