+
+  "
+  If none of the three (top, height, bottom) are 'auto':
+  If both 'margin-top' and 'margin-bottom' are 'auto',
+  solve the equation under the extra constraint that
+  the two margins get equal values.
+  "
+  10.6.4 Absolutely positioned, non-replaced elements

+
+  So:
+
+      0px       : top
+  +
+      (solve)   : margin-top
+  +
+      0px       : border-top

+      0px       : padding-top
+  +
+     34px       : height (constrained by max-height)
+  +
+      0px       : padding-bottom
+  +
+      0px       : border-bottom
+  +
+      (solve)   : margin-bottom
+  +
+      0px       : bottom
+  =============
+    100px       : height of containing block

+  Therefore, margin-top and margin-bottom used values are
