CSS GUIDE -MOZ-USER-MODIFY

Summary

-moz-user-modify is a Mozilla property extension to CSS that is used to determine whether or not an element may be modified.

Media: interactive

Possible uses include:

• update forms which should prohibit modification of certain content, but wish to utilize the same look-and-feel as the input form (for example, textbox usage).
• template pages

Syntax

TARGET_ELEMENT{-moz-user-modify: inherit;}
TARGET_ELEMENT{-moz-user-modify: read-only;}
TARGET_ELEMENT{-moz-user-modify: read-write;}
TARGET_ELEMENT{-moz-user-modify: write-only;}

Legal Values

Value	Description
inherit	Inherit the value from parent element.
read-only	Allow for viewing, selecting and copying the element contents. This has been tested in FF2.0 and doesn't work.
read-write	Allow for viewing, selecting, copying and editing the element contents.
write-only	Allow for selecting and editing the element contents.

Usage Examples

This sample code provides a textbox which allows the user to type and modify content, but does not allow for the cut, copy and paste facilities:

<form method="post" action="foo">
 <span style="-moz-user-modify:write-only;">
  <input type="text" name="tb1" value="qwerty" />
 </span>
</form>
