Remarks

The onresize event fires for block and inline objects with layout, even if document or CSS (cascading style sheets) property values are changed. Objects have layout when measurements such as the height and width attributes are set, or when the position of the object is set. Intrinsic objects, such as button, and windowed objects, such as window and iframe, fire as expected. This event does not fire for files with embedded controls.

Resizing HTML applications also fires the onresize event.
