:-moz-window-inactive
Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.
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.

<p>This is a box!</p>
</div>

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