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.
Summary
The -moz-user-modify
property determines whether or not the content of an element can be edited by a user. This property is related to the contenteditable
attribute. A similar property user-focus
was proposed in early drafts of a predecessor of the CSS3 UI specification but was rejected by the working group.
