Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
The CSSValueList interface derives from the CSSValue interface and provides the abstraction of an ordered collection of CSS values.
Note: This interface was part of an attempt to create a typed CSS Object Model. This attempt has been abandoned, and most browsers do not implement it.
To achieve your purpose, you can use:
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.
Inherits properties from its parent, CSSValue.
CSSValueList.length Read only Deprecated
An unsigned long representing the number of CSSValues in the list.
CSSValueList.item() Deprecated
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.
This feature was originally defined in the DOM Style Level 2 specification, but has been dropped from any standardization effort since then.
It has been superseded by a modern, but incompatible, CSS Typed Object Model API that is now on the standard track.
