| 19 width: 200px; |
| 20 } |
| 21 div div |
| 22 { |
| 23 background: blue; |
| 24 bottom: 200px; |
| 25 height: auto; |
| 26 margin-bottom: auto; |
| 27 margin-top: auto; |
| 28 position: absolute; |
| 29 top: auto; |

| 32 |
| 33 /* |
| 34 |
| 35 auto (to solve) : top |
| 36 + |
| 37 auto (to solve): margin-top |
| 38 + |
| 39 0 : border-top-width |
| 40 + |
| 41 0 : padding-top |
| 42 + |
| 43 auto (to solve) : height |
| 44 + |
| 45 0 : padding-bottom |
| 46 + |
| 47 0 : border-bottom-width |
| 48 + |
| 49 auto (to solve): margin-bottom |
| 50 + |
| 51 200px : bottom |
| 52 ============= |
| 53 300px : height of containing block |
| 54 |
| 55 " |
| 56 'top' and 'height' are 'auto' and 'bottom' is not 'auto', |
| 57 then the height is based on the content per 10.6.7, |
| 58 set 'auto' values for 'margin-top' and 'margin-bottom' to 0, |
| 59 and solve for 'top' |
| 60 " |
| 61 |
| 62 so this brings: |
| 63 |
| 64 |
| 65 auto (to solve) : top |
| 66 + |
| 67 0 (solved): margin-top |
| 68 + |
| 69 0 : border-top-width |
| 70 + |
| 71 0 : padding-top |
| 72 + |
| 73 100px (solved: based on content) : height |
| 74 + |
| 75 0 : padding-bottom |
| 76 + |
| 77 0 : border-bottom-width |
| 78 + |
| 79 0 (solved) : margin-bottom |
| 80 + |
| 81 200px : bottom |
| 82 ============= |
| 83 300px : height of containing block |
| 84 |
| 85 so top will use 0px |
