CSS -webkit-user-drag property

- UNOFF

The non-standard -webkit-user-drag CSS property can be used to either make an element draggable or explicitly non-draggable (like links and images). See the standardized draggable attribute/property for the recommended alternative method of accomplishing the same functionality.

Webkit and blink-based mobile browsers recognize the property but it does not appear to have any effect.

There is currently no unprefixed user-drag or other version of the property implemented in browsers or on a standards track as the HTML draggable attribute/property is the preferred solution.
