<meta content="Margin-top of following siblings of a block on which 'clear' has been set (to a different value than 'none') must not be substracted when calculating clearance. When an element's own margins collapse, and that element has had clearance applied to it, its top margin collapses with the adjoining margins of following siblings." name="assert" />
