+  <div class="desc"><p>Returns the height of the framebuffer in pixels — the number of drawable rows. Use it, together with <code>Screen.width</code>, to position elements relative to the bottom or vertical center of the screen instead of assuming a fixed size. A common use is keeping a moving object on screen by clamping its pixel row against this value. It takes no arguments and can be read during any handler.</p></div>
