| #div1 |
| { |
| color: orange; |
| font: 100px/1 Ahem; |
| height: 300px; |
| position: relative; |
| width: 200px; |
| } |
| div div |
| { |
| background: blue; |
| bottom: 200px; |
| height: auto; |
| margin-bottom: auto; |
| margin-top: auto; |
| position: absolute; |
| top: auto; |
| width: 100%; |
| } |
| |
| /* |
| |
| auto (to solve) : top |
| + |
| auto (to solve): margin-top |
| + |
| 0 : border-top-width |
| + |
| 0 : padding-top |
| + |
| auto (to solve) : height |
| + |
| 0 : padding-bottom |
| + |
| 0 : border-bottom-width |
| + |
| auto (to solve): margin-bottom |
| + |
| 200px : bottom |
| ============= |
| 300px : height of containing block |
| |
| " |
| 'top' and 'height' are 'auto' and 'bottom' is not 'auto', |
| then the height is based on the content per 10.6.7, |
| set 'auto' values for 'margin-top' and 'margin-bottom' to 0, |
| and solve for 'top' |
| " |
| |
| so this brings: |
| |
| |
| auto (to solve) : top |
| + |
| 0 (solved): margin-top |
| + |
| 0 : border-top-width |
| + |
| 0 : padding-top |
| + |
| 100px (solved: based on content) : height |
| + |
| 0 : padding-bottom |
| + |
| 0 : border-bottom-width |
| + |
| 0 (solved) : margin-bottom |
| + |
| 200px : bottom |
| ============= |
| 300px : height of containing block |
| |
| so top will use 0px |
