| 21 { |
| 22 background: orange; |
| 23 bottom: auto; |
| 24 height: 1in; |
| 25 margin-bottom: auto; |
| 26 margin-top: auto; |
| 27 position: absolute; |
| 28 top: auto; |
| 29 width: 100%; |
| 30 } |
| 31 |
| 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 1in : height |
| 44 + |
| 45 0 : padding-bottom |
| 46 + |
| 47 0 : border-bottom-width |
| 48 + |
| 49 auto (to solve): margin-bottom |
| 50 + |
| 51 auto (to solve) : bottom |
| 52 ============= |
| 53 3in : height of containing block |
| 54 |
| 55 |
| 56 " |
| 57 'top' and 'bottom' are 'auto' and 'height' is not 'auto', |
| 58 then set 'top' to the static position, |
| 59 set 'auto' values for 'margin-top' and 'margin-bottom' to 0, |
| 60 and solve for 'bottom' |
| 61 " |
| 62 |
| 63 so this brings: |
| 64 |
| 65 0 (solved static position) : top |
| 66 + |
| 67 0 (solved): margin-top |
| 68 + |
| 69 0 : border-top-width |
| 70 + |
| 71 0 : padding-top |
| 72 + |
| 73 1in : height |
| 74 + |
| 75 0 : padding-bottom |
| 76 + |
| 77 0 : border-bottom-width |
| 78 + |
| 79 0 (solved): margin-bottom |
| 80 + |
| 81 auto (to solve) : bottom |
| 82 ============= |
| 83 3in : height of containing block |
| 84 |
| 85 So, bottom must use 2in in order to balance the equation |
