+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.
+
+3. 'width' and 'right' are 'auto' and 'left' is not 'auto', then the width is shrink-to-fit . 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:
+
+    160px : top: auto: set to static position
+  +
+      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
+  +
+  (solve) : bottom: auto
+    =====================
+    320px : height of containing block
+
+gives us:
+
+    160px : top: auto: set to static position
+  +
+      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
+  +
+  (solve) : bottom: auto
+    =====================

+
+And so computed bottom value must be 80px .

+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.
+
+3. 'width' and 'right' are 'auto' and 'left' is not 'auto', then the width is shrink-to-fit . 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:
+
+    160px : top: auto: set to static position
+  +
+      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
+  +
+  (solve) : bottom: auto
+    =====================
+    320px : height of containing block
+
+gives us:
+
+    160px : top: auto: set to static position
+  +
+      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
+  +
+  (solve) : bottom: auto
+    =====================
+    320px : height of containing block
+
+And so computed bottom value must be 80px .

+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

+
+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.

+"
+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 : margin-bottom
+  +
+    160px : bottom
+    =====================
+    320px : height of containing block
+
+gives us:

+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.
+
+"
+2. 'left' and 'right' are 'auto' and 'width' is not 'auto', then if the 'direction' property of the element establishing the static-position containing block is 'ltr' set 'left' to the static position, otherwise set 'right' to the static position. Then solve for 'left' (if 'direction is 'rtl') or 'right' (if 'direction' is 'ltr').
+"
+
+'top' + 'margin-top' + 'border-top-width' + 'padding-top' + 'height' + 'padding-bottom' + 'border-bottom-width' + 'margin-bottom' + 'bottom' = height of containing block
+
+So:
+
+    160px : top: auto: set to static position
+  +
+      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 80px .

+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.
+
+"
+3. 'width' and 'right' are 'auto' and 'left' is not 'auto', then the width is shrink-to-fit . 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
+  +
+  (based on the content) : height: auto
+  +
+      0px : padding-bottom
+  +
+      0px : border-bottom-width
+  +
+      0px : margin-bottom
+  +
+  (solve) : bottom: auto
+    =====================
+    320px : height of containing block
+
+gives us:
+
+     80px : top
+  +
+      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
+  +
+  (solve) : bottom: auto
+    =====================
+    320px : height of containing block
+
+And so computed bottom value must be 160px .

+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.
+
+"
+3. 'width' and 'right' are 'auto' and 'left' is not 'auto', then the width is shrink-to-fit . 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
+  +
+  (based on the content) : height: auto
+  +
+      0px : padding-bottom
+  +
+      0px : border-bottom-width
+  +
+      0px : margin-bottom
+  +
+  (solve) : bottom: auto
+    =====================
+    320px : height of containing block
+
+gives us:
+
+     80px : top
+  +
+      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
+  +
+  (solve) : bottom: auto
+    =====================
+    320px : height of containing block
+
+And so computed bottom value must be 160px .

+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 none of the three is 'auto': If both 'margin-left' and 'margin-right' are 'auto', solve the equation under the extra constraint that the two margins get equal values, unless this would make them negative, in which case when direction of the containing block is 'ltr' ('rtl'), set 'margin-left' ('margin-right') to zero and solve for 'margin-right' ('margin-left'). If one of 'margin-left' or 'margin-right' is 'auto', solve the equation for that value. If the values are over-constrained, ignore the value for 'left' (in case the 'direction' property of the containing block is 'rtl') or 'right' (in case 'direction' is 'ltr') and solve for that value.
+"
+
+'top' + 'margin-top' + 'border-top-width' + 'padding-top' + 'height' + 'padding-bottom' + 'border-bottom-width' + 'margin-bottom' + 'bottom' = height of containing block
+
+So:
+
+    160px : top
+  +
+      0px : margin-top
+  +
+      0px : border-top-width
+  +
+      0px : padding-top
+  +
+     80px : height
+  +
+      0px : padding-bottom
+  +
+      0px : border-bottom-width
+  +
+      0px : margin-bottom
+  +
+    160px : bottom
+    =====================
+    320px : height of containing block
+
+gives us:
+
+  (solve) : top
+  +
+      0px : margin-top
+  +
+      0px : border-top-width
+  +
+      0px : padding-top

+  +
+    160px : bottom

+

+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.
+
+3. 'width' and 'right' are 'auto' and 'left' is not 'auto', then the width is shrink-to-fit . 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:
+
+    160px : top: auto: set to static position
+  +
+      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
+  +
+  (solve) : bottom: auto
+    =====================
+    320px : height of containing block
+
+gives us:
+
+    160px : 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
+  +
+  (solve) : bottom: auto
+    =====================
+    320px : height of containing block
+
+And so computed bottom value must be 80px .

+
+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.

+"
+3. 'width' and 'right' are 'auto' and 'left' is not 'auto', then the width is shrink-to-fit . 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
+  +

+  (based on the content) : height: auto
+  +
+      0px : padding-bottom
+  +
+      0px : border-bottom-width
+  +
+      0px : margin-bottom
+  +
+  (solve) : bottom: auto
+    =====================
+    320px : height of containing block
+
+gives us:
+
+     80px : top
+  +
+      0px : margin-top
+  +
+      0px : border-top-width
+  +

+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'

+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 the values are over-constrained, ignore the value for 'left' (in case the 'direction' property of the containing block is 'rtl') or 'right' (in case 'direction' is 'ltr') and solve for that value.
+"
+
+'top' + 'margin-top' + 'border-top-width' + 'padding-top' + 'height' + 'padding-bottom' + 'border-bottom-width' + 'margin-bottom' + 'bottom' = height of containing block
+
+So:
+
+    160px : top
+  +
+      0px : margin-top
+  +
+      0px : border-top-width
+  +

+      0px : margin-bottom
+  +
+    160px : bottom
+    =====================
+    320px : height of containing block
+
+gives us:

+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 none of the three is 'auto': If both 'margin-left' and 'margin-right' are 'auto', solve the equation under the extra constraint that the two margins get equal values, unless this would make them negative, in which case when direction of the containing block is 'ltr' ('rtl'), set 'margin-left' ('margin-right') to zero and solve for 'margin-right' ('margin-left'). If one of 'margin-left' or 'margin-right' is 'auto', solve the equation for that value. If the values are over-constrained, ignore the value for 'left' (in case the 'direction' property of the containing block is 'rtl') or 'right' (in case 'direction' is 'ltr') and solve for that value.
+"
+
+'top' + 'margin-top' + 'border-top-width' + 'padding-top' + 'height' + 'padding-bottom' + 'border-bottom-width' + 'margin-bottom' + 'bottom' = height of containing block
+
+So:
+
+    160px : top
+  +
+      0px : margin-top
+  +
+      0px : border-top-width
+  +
+      0px : padding-top
+  +
+     80px : height
+  +
+      0px : padding-bottom
+  +
+      0px : border-bottom-width
+  +
+      0px : margin-bottom
+  +
+    160px : bottom
+    =====================
+    320px : height of containing block
+
+gives us:
+
+  (solve) : top
+  +
+      0px : margin-top
+  +
+      0px : border-top-width
+  +
+      0px : padding-top
+  +
+     80px : height
+  +
+      0px : padding-bottom
+  +
+      0px : border-bottom-width
+  +
+      0px : margin-bottom
+  +
+    160px : bottom
+    =====================
+    320px : height of containing block
+
+And so computed top value must be 80px .
