  <meta content="An element that does not have clearance applied to it can collapse its top margin with its parent block's bottom margin. Margins of a 'collapsed through' box without clearance applied to it can collapse with its parent block's bottom margin. An element with clear set to it (to other than 'none') can only create a clearance if and when there is a preceding floated block." name="assert" />
