Deprecated
This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. 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.
Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The -moz-user-modify
property has no effect. It was originally planned to determine whether or not the content of an element can be edited by a user.
/* Keyword values */ -moz-user-modify: read-only; -moz-user-modify: read-write; -moz-user-modify: write-only; /* Global values */ -moz-user-modify: inherit; -moz-user-modify: initial; -moz-user-modify: unset;
This property is related to the contenteditable
attribute.
