:-moz-window-inactive
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.
The :-moz-window-inactive
CSS pseudo-class is a Mozilla extension that matches any element while it's in an inactive window.
:-moz-window-inactive
works in content HTML documents, too.
Note: Prior to the addition of this pseudo-class, giving different styles to background windows was achieved by setting an attribute (active="true"
) on the top-level XUL chrome window. This attribute is no longer used.
Syntax
:-moz-window-inactive {
/* ... */
}
Examples
This example alters the appearance of a box's background depending on whether its window is active or not.

#mybox {
background: linear-gradient(to bottom, yellow, cyan);
width: 200px;
