pageX/Y gives the coordinates relative to the element in CSS pixels. The MouseEvent.screenX read-only property provides the horizontal coordinate of the mouse pointer in global (screen) coordinates.

This point does not move even if the user moves a scrollbar from within the browser.įor a visual on which browsers support which properties: Relative to the upper left edge of the content area ( the viewport) of the browser window.
