| div#containing-block |
| { |
| background: red url("support/bg-red-2col-2row-320x320.png"); |
| color: transparent; |
| direction: rtl; |
| font: 80px/1 Ahem; |
| height: 320px; |
| position: relative; |
| width: 320px; |
| } |
| |
| div#containing-block > span |
| { |
| background-color: green; |
| bottom: auto; |
| height: 1em; |
| position: absolute; |
| top: auto; |
| width: 1em; |
| writing-mode: vertical-lr; |
| } |

| 2. 'top' and 'bottom' are 'auto' and 'height' is not 'auto', then set 'top' to the static position, set 'auto' values for 'margin-top' and 'margin-bottom' to 0, and solve for 'bottom' |
| " |
| |
| 'top' + 'margin-top' + 'border-top-width' + 'padding-top' + 'height' + 'padding-bottom' + 'border-bottom-width' + 'margin-bottom' + 'bottom' = height of containing block |
| |
| So: |
| |
| 80px : top: auto: set to static position |
| + |
| 0px : margin-top |
| + |
| 0px : border-top-width |
| + |
| 0px : padding-top |
| + |
| 80px : height |
| + |
| 0px : padding-bottom |
| + |
| 0px : border-bottom-width |
| + |
| 0px : margin-bottom |
| + |
| (solve) : bottom: auto |
| ===================== |
| 320px : height of containing block |
| |
| And so computed bottom value must be 160px . |
