| /* |
| |
| 0.5in : 'top' |
| + |
| 0.5in : 'margin-top' |
| + |
| 0 : 'border-top-width' |
| + |
| 0 : 'padding-top' |
| + |
| 1in : 'height' (used width) / (intrinsic ratio) |
| + |
| 0 : 'padding-bottom' |
| + |
| 0 : 'border-bottom-width' |
| + |
| 0.5in : 'margin-bottom' |
| + |
| 1in : 'bottom' |
| =========== |
| 436px : height of containing block (0px) |
| |
| So, bottom has to be ignored and forced to have the value that |
| will balance the equation. So, this brings up |
| |
| 0.5in : 'top' |
| + |
| 0.5in : 'margin-top' |
| + |
| 0 : 'border-top-width' |
| + |
| 0 : 'padding-top' |
| + |
| 1in : 'height' (used width) / (intrinsic ratio) |
| + |
| 0 : 'padding-bottom' |
| + |
| 0 : 'border-bottom-width' |
| + |
| 0.5in : 'margin-bottom' |
| + |
| (solve): 'bottom' |
| =================== |
| 240px : height of containing block (0px) |
| |
| So the solved bottom value should be -240px |
