| 11 `core-splitter` provides a split bar and dragging on the split bar | |
| 12 will resize the sibling element. Use its `direction` property to indicate | |
| 13 which sibling element to be resized and the orientation. Usually you would want | |
| 14 to use `core-splitter` along with flex layout so that the other sibling | |
| 15 element can be _flexible_. | |
| 16 | |
| 17 Example: | |
| 18 | |
| 19 <div horizontal layout> | |
| 20 <div>left</div> | |
| 21 <core-splitter direction="left"></core-splitter> | |
| 22 <div flex>right</div> | |
| 23 </div> | |
| 24 | |
| 25 In the above example, dragging the splitter will resize the _left_ element. And | |
| 26 since the parent container is a flexbox and the _right_ element has | |
| 27 `flex`, the _right_ element will be auto-resized. | |
| 28 | |
| 29 For horizontal splitter set `direction` to `up` or `down`. | |
| 30 | |
| 31 Example: | |
| 32 | |
| 33 <div vertical layout> | |
| 34 <div>top</div> | |
| 35 <core-splitter direction="up"></core-splitter> | |
| 36 <div flex>bottom</div> | |
| 37 </div> | |
