You could always read the book...
Napoleon didn't get his way on:
-obliging parents to provide a dowry for daughters.
-giving grandparents the right to protect their grandchildren from ill-treatment by their parents.
Napoleon also attempted to get the French principle of 'legal death' changed in the Code. He was outvoted.
So, there's four items.
Again, you might actually want to do research on the subject. It is very interesting.
