| 59 =========== |
| 60 436px : height of containing block (0px) |

| 62 So, bottom has to be ignored and forced to have the value that |
| 63 will balance the equation. So, this brings up |

| 67 0.5in : 'margin-top' |

| 69 0 : 'border-top-width' |

| 77 0 : 'border-bottom-width' |
| 78 + |
| 79 0.5in : 'margin-bottom' |

| 81 (solve): 'bottom' |
| 82 =================== |
| 83 240px : height of containing block (0px) |
