MDN’s new design is in Beta! A sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

Summary

Gets the X 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 nsIDOMWindowUtils.screenPixelsPerCSSPixel property.

Syntax

screenX = window.mozInnerScreenX;

Value

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

Specification

Not part of any W3C technical specification or recommendation.
