-Auto heights for block formatting context roots</h3>
-
-	In certain cases (see, e.g., <a href="#abs-non-replaced-height">The height of
-	absolute or fixed positioned, non-replaced element</a> above), the height
-	of an element that establishes a block formatting context is computed as follows:
-
-	If it only has inline-level children, the height is the distance between the
-	top of the topmost line box and the bottom of the bottommost line box.
-
-	If it has block-level children, the height is the distance between the top
-	margin-edge of the topmost block-level child box and the bottom margin-edge of
-	the bottommost block-level child box.
-
-	Absolutely positioned children are ignored, and relatively positioned boxes are
-	considered without their inset. Note that the child box may be an <a href="https://www.w3.org/TR/CSS2/visuren.html#anonymous-block-level">anonymous block box</a>.
-
-	In addition, if the element has any floating descendants whose bottom margin edge
-	is below the element’s bottom content edge, then the height is increased to
-	include those edges. Only non-positioned <a>floats</a> that
-	participate in this block formatting context are taken into account, e.g.,
-	<a>floats</a> inside absolutely positioned descendants or
-	other <a>floats</a> are not.
