The user-modify property has no effect in Firefox. It was originally planned to determine whether or not the content of an element can be edited by a user.

[!WARNING] This property has been replaced by the contenteditable attribute.

user-modify: read-only;
user-modify: read-write;
user-modify: write-only;

/* Global values */
user-modify: inherit;
user-modify: initial;
user-modify: revert;
user-modify: unset;

This property is specified as one of the following keyword values:

  • read-only
    • : Default value. Contents are read-only.
  • read-write
    • : The user is able to read and write contents.
  • read-write-plaintext-only
    • : Same as read-write, but rich text formatting will be lost.
  • write-only
    • : The user is able to edit the content, but not to read it.
