onmouseover vs. onmousemove
Am I right in my understanding here?
The onmouseover event occurs only once at the exact time the mouse
pointer enters into an object's boundaries. In contrast, onmousemove
occurs from the time the mouse pointer enters an object's boundaries
and occurs everytime the mouse pointer moves one pixel as long as it is
inside the object's boundaries.
