y property indicates the offset from the bottom edge of
the destination surface (typically a
XRWebGLLayer to the bottom edge of
the viewport within the surface into which WebXR content is to be rendered. The
x property identifies the
component of the origin, and its is given by the
The offset from the bottom edge of the rendering surface to the bottom edge of the viewport, in pixels.
Note: Although other web APIs typically consider the
axis to begin at the top and grow larger progressing downward, WebGL reverses this,
y growing larger as it goes upward on the screen.

XRViewport page for examples.
