Web/API/Window/mozInnerScreenY

Summary

Gets the Y coordinate of the top-left corner of the window's viewport, in screen coordinates.

Note: This coordinate is reported in CSS pixels, not in hardware pixels. That means it can be affected by the zoom level; to compute the actual number of physical screen pixels, you should use the [[../../../../Mozilla/Tech/XPCOM/Reference/Interface/nsIDOMWindowUtils|nsIDOMWindowUtils.screenPixelsPerCSSPixel]] property.

Syntax

screenY = window.mozInnerScreenY;

Value

• screenY stores the window.mozInnerScreenY property value.
• The window.mozInnerScreenY property is a floating point, read-only value; it has no default value.

Specification

Not part of any W3C technical specification or recommendation.
