     43 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').
     44 "
     45 
     46 'left' + 'margin-left' + 'border-left-width' + 'padding-left' + 'width' + 'padding-right' + 'border-right-width' + 'margin-right' + 'right' = width of containing block
     47 
     48 So:
     49 
     50   (solve) : left: auto
     51   +
     52       0px : margin-left
     53   +
     54       0px : border-left-width
     55   +
     56       0px : padding-left
     57   +
     58      80px : width
     59   +
     60       0px : padding-right
     61   +
     62       0px : border-right-width
     63   +
     64       0px : margin-right
     65   +
     66     160px : right: auto
     67     =====================
     68     320px : width of containing block
     69 
     70 And so computed left value must be 80px .
