There are two main types of margin collapse:

• Collapsing margins between adjacent elements
• Collapsing margins between parent and child elements

Using a padding or border will prevent collapse only when Collapsing is between parent and children. Also, any value of overflow different from its default (visible) applied to the parent will prevent collapse.

Thus, both overflow: auto and overflow: hidden will have the same effect.
