<!--
fixed-height container so percentage heights compute to different
(i.e., nonzero) values
fixed-width container so that percentages for margin-top and
margin-bottom are all relative to the same size container (rather than
one that depends on whether we're tall enough to need a scrollbar)
Use a 20px font size and line-height so that percentage line-height
and vertical-align doesn't accumulate rounding error.
