| 14 app-header-layout is a wrapper element that positions an app-header and other co
ntent. This | |
| 15 element uses the document scroll by default, but it can also define its own scro
lling region. | |
| 16 | |
| 17 Using the document scroll: | |
| 18 | |
| 19 ```html | |
| 20 <app-header-layout> | |
| 21 <app-header fixed condenses effects="waterfall"> | |
| 22 <app-toolbar> | |
| 23 <div title>App name</div> | |
| 24 </app-toolbar> | |
| 25 </app-header> | |
| 26 <div> | |
| 27 main content | |
| 28 </div> | |
| 29 </app-header-layout> | |
| 30 ``` | |
| 31 | |
| 32 Using an own scrolling region: | |
| 33 | |
| 34 ```html | |
| 35 <app-header-layout has-scrolling-region style="width: 300px; height: 400px;"> | |
| 36 <app-header fixed condenses effects="waterfall"> | |
| 37 <app-toolbar> | |
| 38 <div title>App name</div> | |
| 39 </app-toolbar> | |
| 40 </app-header> | |
| 41 <div> | |
| 42 main content | |
| 43 </div> | |
| 44 </app-header-layout> | |
