| 42 + right : 100px |
| 43 ==================================== |
| 44 width of containing block : 200px |
| 45 |
| 46 So, margin-left and margin-right would be each -50px at this point. |
| 47 |
| 48 "...unless this would make them (the two margins) negative |
| 49 in which case when direction of the containing block is |
| 50 'ltr' ('rtl'), set 'margin-left' ('margin-right') to zero and |
| 51 solve for 'margin-right' ('margin-left')." |
| 52 |
| 53 So, under such extra constraint, 'margin-left' must become 0 |
| 54 and 'margin-right' must become -100px. |
