CSS GUIDE -MOZ-USER-INPUT

Summary

-moz-user-input is a Mozilla property extension to CSS that is used to determine whether or not an element may be selected with input focus.

Media: interactive

Possible uses include:

• Displaying a textbox that should not even allow the cursor within it--useful to block the content from being copied
• A form that should disable input for a textbox (pre-defined value).

Syntax

TARGET_ELEMENT{-moz-user-input: inherit;}
TARGET_ELEMENT{-moz-user-input: disabled;}
TARGET_ELEMENT{-moz-user-input: enabled;}
TARGET_ELEMENT{-moz-user-input: none;}

Legal Values

Value	Description
inherit	Inherit the value from the parent element.
disabled	The element will not accept user input.
enabled	The element accepts user input.
none	The element does not respond to user input, and as such, neither disabled nor enabled are applicable.

Usage Examples

This sample code provides a textbox which does not allow input focus (left mouse click and subsequent display of the cursor):

<span style="-moz-user-input: disabled;">
 <input type="text" name="tb1" value="qwerty" />
</span>

Notes

This property is similar to the user-input property of CSS3.

According to the W3C, "any settings for the user-input property are ignored when inside a style declaration selected by either the :enabled or :disabled pseudo-classes. This is to avoid the obvious infinite loop of setting user-input:disabled on a :enabled pseudo-class for example." [1]
