+ + border-right-width : 0
+ + margin-right : solve (auto)
+ + right : 100px
+ ====================================
+ width of containing block : 200px
+
+ So, margin-left and margin-right would be each -50px at this point.
+
+ "...unless this would make them (the two margins) 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')."
+
+ So, under such extra constraint, 'margin-left' must become 0
+ and 'margin-right' must become -100px.
