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.
|
|
|
|
"
|
|
If all three of 'left', 'width', and 'right' are 'auto': First set any 'auto' values for 'margin-left' and 'margin-right' to 0. Then, if the 'direction' property of the element establishing the static-position containing block is 'ltr' set 'left' to the static position and apply rule number three below; otherwise, set 'right' to the static position and apply rule number one below.
|
|
|
|
1. 'left' and 'width' are 'auto' and 'right' is not 'auto', then the width is shrink-to-fit. Then solve for 'left'
|
|
"
|
|
|
|
'top' + 'margin-top' + 'border-top-width' + 'padding-top' + 'height' + 'padding-bottom' + 'border-bottom-width' + 'margin-bottom' + 'bottom' = height of containing block
|
|
|
|
So:
|
|
|
|
(solve) : top: auto
|
|
+
|
|
0px : margin-top
|
|
+
|
|
0px : border-top-width
|
|
+
|
|
0px : padding-top
|
|
+
|
|
(based on the content) : height: auto
|
|
+
|
|
0px : padding-bottom
|
|
+
|
|
0px : border-bottom-width
|
|
+
|
|
0px : margin-bottom
|
|
+
|
|
160px : bottom: auto: set to static position
|
|
=====================
|
|
320px : height of containing block
|
|
|
|
gives us:
|
|
|
|
(solve) : top: auto
|
|
+
|
|
0px : margin-top
|
|
+
|
|
0px : border-top-width
|
|
+
|
|
0px : padding-top
|
|
+
|
|
80px : (based on the content) : height: auto
|
|
+
|
|
0px : padding-bottom
|
|
+
|
|
0px : border-bottom-width
|
|
+
|
|
0px : margin-bottom
|
|
+
|
|
160px : bottom: auto: set to static position
|
|
=====================
|
|
320px : height of containing block
|
|
|
|
And so computed top value must be 80px .
