Question Card Drag and Drop and Area Detection Problem

Hello Unity Community,



I have already implemented drag and drop to the gray area(It is now depeding on the pointer event data) but I would like to make it when the aqua card's border hit the gray area's border, it immediately snap to the gray area rather than keep track of the mouse cursor.

I have tried collider, but without pointer event data, how can I set the position of the card to snap to the gray area? Or is there any other way of doing this without using a collider?

I would be grateful if you can explain it with some code.
