+  the top of the page).  Together these items will line up to form a
+  rectangle.
+
+  This test only tests the 'top', 'bottom', 'text-top', 'text-bottom',
+  'baseline', <length>, and <percentage> values of 'vertical-align'.  It
+  does not test 'sub', 'super', or 'middle', and it does not test
+  anything relative to actual font metrics.
