+"
+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'
+"
+
+'left' + 'margin-left' + 'border-left-width' + 'padding-left' + 'width' + 'padding-right' + 'border-right-width' + 'margin-right' + 'right' = width of containing block
+
+So:
+
+    160px : left: auto: set to static position
+  +
+      0px : margin-left
+  +
+      0px : border-left-width
+  +
+      0px : padding-left
+  +
+  (shrink-to-fit) : width: auto
+  +
+      0px : padding-right
+  +
+      0px : border-right-width
+  +
+      0px : margin-right
+  +
+  (solve) : right: auto
+    =====================
+    320px : width of containing block
+
+gives us:
+
+    160px : left: auto: set to static position
+  +
+      0px : margin-left
+  +
+      0px : border-left-width
+  +
+      0px : padding-left
+  +
+     80px : (shrink-to-fit) : width: auto
+  +
+      0px : padding-right
+  +
+      0px : border-right-width
+  +
+      0px : margin-right
+  +
+  (solve) : right: auto
+    =====================
+    320px : width of containing block
+
+And so computed right value must be 80px .
