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 .
