"
1. [If] 'left' and 'width' are 'auto' and 'right' is not 'auto', then the width is shrink-to-fit. Then solve for 'left'

10.3.7 Absolutely positioned, non-replaced elements
http://www.w3.org/TR/CSS21/visudet.html#abs-non-replaced-width
So:
auto : left
+
0px : margin-left
+
25px : border-left-width
+
0px : padding-left
+
auto : width
+
0px : padding-right
+
75px : border-right-width
+
0px : margin-right
+
80% : right
====================
500px : width of containing block (width of Initial Containing Block)
becomes
(solve) : left
+
0px : margin-left
+
25px : border-left-width
+
0px : padding-left
+
0px : width (shrink-to-fit)
+
0px : padding-right
+
75px : border-right-width
+
0px : margin-right
+
400px : right (80% of 500px == 400px)
====================
500px : width of containing block (width of Initial Containing Block)
so used left offset value must be 0 .
