		 auto (to solve) : top
	+
		 auto (to solve): margin-top
	+
		 0 : border-top-width
	+
		 0 : padding-top
	+
		 auto (to solve) : height
	+
		 0 : padding-bottom
	+
		 0 : border-bottom-width
	+
		 auto (to solve): margin-bottom
	+
		200px : bottom
	=============
		300px  : height of containing block

		"
		'top' and 'height' are 'auto' and 'bottom' is not 'auto',
		then the height is based on the content per 10.6.7,
		set 'auto' values for 'margin-top' and 'margin-bottom' to 0,
		and solve for 'top'
		"

		so this brings:


		 auto (to solve) : top
	+
		 0 (solved): margin-top
	+
		 0 : border-top-width
	+
		 0 : padding-top
	+
		 100px (solved: based on content) : height
	+
		 0 : padding-bottom
	+
		 0 : border-bottom-width
	+
		 0 (solved) : margin-bottom
	+
		200px : bottom
	=============
		300px  : height of containing block

		so top will use 0px
