-moz-user-input was one of the proposals leading to the proposed CSS 3 user-input property, which has not yet reached Candidate Recommendation (call for implementations).

For elements that normally take user input, such as a <textarea>, the initial value of -moz-user-input is enabled.

Syntax

/* Keyword values */
-moz-user-input: none;
-moz-user-input: enabled;
-moz-user-input: disabled;

/* Global values */
-moz-user-input: inherit;
-moz-user-input: initial;
-moz-user-input: unset;

Values

none: The element does not respond to user input, and it does not become :active.
enabled: The element accepts user input. For textboxes, this is the default behavior.
disabled: The element does not accept user input. However, this is not the same as setting disabled to true, in that the element is drawn normally.

Formal syntax

auto | none | enabled | disabled

Examples

input.example {
  /* the user will be able to select the text, but not change it. */
  -moz-user-input: disabled;
}
