onresizeNN 4 IE 4 DOM 2  

Bubbles: Yes; Cancelable: No  

Fires after an element or object is resized by the user or script control. Note that resizing a window may force other elements in the page to resize themselves. In IE, onresize events from those elements bubble to the body and window objects, where a lone onresize event handler may be bombarded by events.

 
Typical Targets

For IE, elements that have dimensions associated with them, plus the window and document objects; for Navigator, the window and document objects.
