<meta name="assert" content="When 'top' is set to the static position and any 'auto' values for top and bottom margin are set to '0', when 'top' and 'bottom' are 'auto' and 'height' is not 'auto'." />

{
background: blue;
height: 3in;
position: relative;
width: 1in;
}

/*
auto (to solve) : top

auto (to solve): margin-top
+
0 : border-top-width
+
0 : padding-top
+
1in : height
+
0 : padding-bottom
+
0 : border-bottom-width
+
auto (to solve): margin-bottom
+
auto (to solve) : bottom
=============
3in : height of containing block
"
'top' and 'bottom' are 'auto' and 'height' is not 'auto',
then set 'top' to the static position,
set 'auto' values for 'margin-top' and 'margin-bottom' to 0,
and solve for 'bottom'
"
so this brings:
0 (solved static position) : top
+
0 (solved): margin-top
+
0 : border-top-width
+
0 : padding-top
+
1in : height
+
0 : padding-bottom
+
0 : border-bottom-width
+
0 (solved): margin-bottom
+
auto (to solve) : bottom
=============
3in : height of containing block
So, bottom must use 2in in order to balance the equation
