| background: red url("support/bg-red-3col-2row-320x320.png"); |
| color: transparent; |
| direction: ltr; |
| font: 80px/1 Ahem; |
| height: 320px; |
| position: relative; |
| width: 320px; |
| } |
| |
| div#containing-block > span |
| { |
| background-color: red; |
| color: green; |
| left: auto; |
| position: absolute; |
| right: 1em; |

| 4. 'left' is 'auto', 'width' and 'right' are not 'auto', then solve for 'left' |
| " |
| |
| 'left' + 'margin-left' + 'border-left-width' + 'padding-left' + 'width' + 'padding-right' + 'border-right-width' + 'margin-right' + 'right' = width of containing block |
| |
| So: |
| |
| (solve) : left: auto |
| + |
| 0px : margin-left |
| + |
| 0px : border-left-width |
| + |
| 0px : padding-left |
| + |
| 80px : width |
| + |
| 0px : padding-right |
| + |
| 0px : border-right-width |
| + |
| 0px : margin-right |
| + |
| 80px : right |
| ===================== |
| 320px : width of containing block |
| |
| And so computed left value must be 160px . |
