| 9 `<core-layout-trbl>` arranges nodes horizontally via absolute positioning. | |
| 10 Set the `vertical` attribute (boolean) to arrange vertically instead. | |
| 11 | |
| 12 `<core-layout-trbl>` arranges it's <b>sibling elements</b>, not | |
| 13 it's children. | |
| 14 | |
| 15 One arranged node may be marked as elastic by giving it a `flex` | |
| 16 attribute (boolean). | |
| 17 | |
| 18 You may remove a node from layout by giving it a `nolayout` | |
| 19 attribute (boolean). | |
| 20 | |
| 21 CSS Notes: | |
| 22 | |
| 23 `padding` is ignored on the parent node. | |
| 24 `margin` is ignored on arranged nodes. | |
| 25 `min-width` is ignored on arranged nodes, use `min-width` on the parent node | |
| 26 instead. | |
| 27 | |
| 28 Example: | |
| 29 | |
| 30 Arrange three `div` into columns. `flex` attribute on Column Two makes that | |
| 31 column elastic. | |
| 32 | |
| 33 <core-layout-trbl></core-layout-trbl> | |
| 34 <div>Column One</div> | |
| 35 <div flex>Column Two</div> | |
| 36 <div>Column Three</div> | |
| 37 | |
| 38 Remember that `<core-layout-trbl>` arranges it's sibling elements, not it's chil
dren. | |
| 39 | |
| 40 If body has width 52 device pixels (in this case, ascii characters), call that 5
2px. | |
| 41 Column One has it's natural width of 12px (including border), Column Three has i
t's | |
| 42 natural width of 14px, body border uses 2px, and Column Two automatically uses t
he | |
| 43 remaining space: 24px. | |
| 44 | |
| 45 |- 52px -| | |
| 46 ---------------------------------------------------- | |
| 47 ||Column One|| Column Two ||Column Three|| | |
| 48 ---------------------------------------------------- | |
| 49 |- 12px -||- (24px) -|| 14px -| | |
| 50 | |
| 51 As the parent node resizes, the elastic column reacts via CSS to adjust it's siz
e. | |
| 52 No javascript is used during parent resizing, for best performance. | |
| 53 | |
| 54 Changes in content or sibling size are not handled automatically. | |
| 55 | |
| 56 ---------------------------------------------------------------- | |
| 57 ||Column One| Column Two |Column Three|| | |
| 58 ---------------------------------------------------------------- | |

| 61 ||Column One|Column Two|Column Three|| | |

| 63 | |
| 64 Arrange in rows by adding the `vertical` attribute. | |
| 65 | |
| 66 Example: | |
| 67 | |
| 68 <core-layout-trbl vertical></core-layout-trbl> | |
| 69 <div>Row One</div> | |
| 70 <div flex>Row Two</div> | |
| 71 <div>Row Three</div> | |
| 72 | |
| 73 This setup will cause Row Two to stretch to fill the container. | |
| 74 | |
| 75 ----------- ----------- | |
| 76 |---------| |---------| | |
| 77 | | | | | |
| 78 |Row One | |Row One | | |
| 79 | | | | | |

| 81 | | | | | |
| 82 |Row Two | |Row Two | | |

| 85 | | | | | |
| 86 |Row Three| | | | |

| 94 Layouts can be nested arbitrarily. | |
| 95 | |
| 96 <core-layout-trbl></core-layout-trbl> | |
| 97 <div>Menu</div> | |
| 98 <div flex> | |
| 99 <core-layout-trbl vertical></core-layout-trbl> | |
| 100 <div>Title</div> | |
| 101 <div>Toolbar</div> | |
| 102 <div flex>Main</div> | |
| 103 <div>Footer</div> | |
| 104 </div> | |
| 105 | |
| 106 Renders something like this | |
