<p> | |
This example shows how pointer events can be specified to fall through or | |
be caught by underlying elements. The transparent box with the black | |
stroke has its 'pointer-events' property set to 'all' so catches all | |
events. The blue box has its 'pointer-events' property set to 'none' so | |
that the events are applied to the green box beneath it. However, the | |
green box handles its pointer events normally so that it events in the | |
area where it overlaps with the red box do not affect the red box because | |
they are captured by the green | |
box. | |
