position: absolute;

/*
0.5in : 'top'
+
0.5in : 'margin-top'
+
0 : 'border-top-width'
+
0 : 'padding-top'
+
1in : 'height' (used width) / (intrinsic ratio)
+
0 : 'padding-bottom'
+
0 : 'border-bottom-width'
+
0.5in : 'margin-bottom'
+
1in : 'bottom'
===========
436px : height of containing block (0px)
So, bottom has to be ignored and forced to have the value that
will balance the equation. So, this brings up
0.5in : 'top'
+
0.5in : 'margin-top'
+
0 : 'border-top-width'
+
0 : 'padding-top'
+
1in : 'height' (used width) / (intrinsic ratio)
+
0 : 'padding-bottom'
+
0 : 'border-bottom-width'
+
0.5in : 'margin-bottom'
+
(solve): 'bottom'
===================
240px : height of containing block (0px)
So the solved bottom value should be -240px
