I’ve got an aissue with 2 divs – both rendered as blocks both have margins of 15px (top div has bottom margin, bottom has top), therefore I expect the gap between to be 30px rather than 15px, is this a correct assumption or am I going mad!?
Cheers

The CSS box model defines the behavior for collapsing margins, and it is expected behavior among all browsers.
