| div div |
| { |
| border: solid green; |
| height: 1in; |

| /* |
| |
| 0.5in : 'top' |
| + |
| 0.5in : 'margin-top' |
| + |
| 3px : 'border-top-width' medium which is often resolved as 3px |
| + |
| 0 : 'padding-top' |
| + |
| 1in : 'height' 50% of height of containing block |
| + |
| 0 : 'padding-bottom' |
| + |
| 3px : 'border-bottom-width' medium which is often resolved as 3px |
| + |
| 0.5in : 'margin-bottom' |
| + |
| 1in : 'bottom' |
| ================ |
| 342px : height of containing block (192px) |
| |
| 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' |
| + |
| 3px : 'border-top-width' medium which is often resolved as 3px |
| + |
| 0 : 'padding-top' |
| + |
| 1in : 'height' 50% of height of containing block |
| + |
| 0 : 'padding-bottom' |
| + |
| 3px : 'border-bottom-width' medium which is often resolved as 3px |
| + |
| 0.5in : 'margin-bottom' |
| + |
| (solve) : 'bottom' |
| ================ |
| -246px : height of containing block (192px) |
| |
| So, the solved bottom value should be -54px . |
