10.3.7 Absolutely positioned, non-replaced elements
So:
auto : left
+
0px : margin-left
+
35px : border-left-width
+
0px : padding-left
+
50px : width
+
0px : padding-right
+
15px : border-right-width
+
0px : margin-right
+
80% : right
====================
500px : width of containing block (width of Initial Containing Block)
becomes
(solve) : left
+
0px : margin-left
+
35px : border-left-width
+
0px : padding-left
+
50px : width
+
0px : padding-right
+
15px : 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 0px .
