CSSValueList: length property

The length read-only property of the CSSValueList interface represents the number of CSSValues in the list. The range of valid values of the indices is 0 to length-1 inclusive.

[!NOTE] This property 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:

• the untyped CSS Object Model, widely supported, or
• the modern CSS Typed Object Model API, less supported and considered experimental.

Value

An unsigned long representing the number of CSSValues.

Specifications

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It has been superseded by a modern, but incompatible, CSS Typed Object Model API that is now on the standard track.
