A left-floated box will shit to the left until its leftmost margin edge (or border edge if margins are absent) touches either the edge of the containing block, or the edge of another floated box. If the size of the floated box exceeds the available horizontal space, the floated box will be shifted down. Non-positioned, non-floated, block-level elements act as if the floated element is not there, since the floated element is out of document flow.
