Solution to "child margin affects parent" in CSS

The browser implementation is that when the parent has no content and the child requests for margin, the parent is brought down instead of child going down.

The solution for these are listed below with their side effects.

• floats, You have to float elements
• border-top, This pushes the parent at least 1px downwards which should then be adjusted with introducing -1px margin to the parent element itself. This can create problems when parent already has margin-top in relative units.
• padding-top, same effect as using border-top
• overflow: hidden, Can't be used when parent should display overflowing content, like a drop down menu
• overflow: auto, Introduces scrollbars for parent element that has (intentionally) overflowing content (like shadows or tool tip's triangle)
