"
Layout calculation rules (such as those in CSS2.1, Section 10.3) that apply to the horizontal dimension in horizontal writing modes instead apply to the vertical dimension in vertical writing modes.
"
7.1 Principles of Layout in Vertical Writing Modes
http://www.w3.org/TR/css-writing-modes-3/#vertical-layout
So here, *-top and *-bottom properties are input into the §10.3.7 algorithms where *-top properties refer to *-left properties in the layout rules and where *-bottom properties refer to *-right properties in the layout rules.
"
6. 'right' is 'auto', 'left' and 'width' are not 'auto', then solve for 'right'
"
'top' + 'margin-top' + 'border-top-width' + 'padding-top' + 'height' + 'padding-bottom' + 'border-bottom-width' + 'margin-bottom' + 'bottom' = height of containing block
So:
80px : top
+
0px : margin-top
+
0px : border-top-width
+
0px : padding-top
+
80px : height
+
0px : padding-bottom
+
0px : border-bottom-width
+
0px : margin-bottom
+
(solve) : bottom: auto
=====================
320px : height of containing block
And so computed bottom value must be 160px .
