====================================
|
|
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.
