| 11 `core-scroll-header-panel` contains a header section and a content section. The |
| 12 header is initially on the top part of the view but it scrolls away with the |
| 13 rest of the scrollable content. Upon scrolling slightly up at any point, the |
| 14 header scrolls back into view. This saves screen space and allows users to |
| 15 access important controls by easily moving them back to the view. |
| 16 |
| 17 __Important:__ The `core-scroll-header-panel` will not display if its parent doe
s not have a height. |
| 18 |
| 19 Using [layout attributes](http://www.polymer-project.org/docs/polymer/layout-att
rs.html), you can easily make the `core-scroll-header-panel` fill the screen |
| 20 |
| 21 <body fullbleed layout vertical> |
| 22 <core-scroll-header-panel flex> |
| 23 <core-toolbar> |
| 24 <div>Hello World!</div> |
| 25 </core-toolbar> |
| 26 </core-scroll-header-panel> |
| 27 </body> |
| 28 |
| 29 or, if you would prefer to do it in CSS, just give `html`, `body`, and `core-scr
oll-header-panel` a height of 100%: |
| 30 |
| 31 html, body { |
| 32 height: 100%; |
| 33 margin: 0; |
| 34 } |
| 35 core-scroll-header-panel { |
| 36 height: 100%; |
| 37 } |
| 38 |
| 39 `core-scroll-header-panel` works well with `core-toolbar` but can use any elemen
t |
| 40 that represents a header by adding a `core-header` class to it. Use the attribu
te |
| 41 or class `content` to delineate the content section. |
| 42 |
| 43 <core-scroll-header-panel> |
| 44 <core-toolbar>Header</core-toolbar> |
| 45 <div content>Content goes here...</div> |
| 46 </core-scroll-header-panel> |
