A is a subset of B if and only if for all elements x of A, x is in B. This is vacuously true, since there are no elements x of the empty set. Hence, the empty set is a subset of the empty set

Proper just means the sets arent equal. So the fact that the empty set is a subset of every set, even though every set isnt empty, means its a proper subset of any non empty set.
