| +# paper-header-panel
|
| +
|
| +`paper-header-panel` contains a header section and a content panel section.
|
| +
|
| +__Important:__ The `paper-header-panel` will not display if its parent does not have a height.
|
| +
|
| +Using [layout classes](http://www.polymer-project.org/docs/polymer/layout-attrs.html), you can make
|
| +the `paper-header-panel` fill the screen
|
| +
|
| +```html
|
| +<body class="fullbleed layout vertical">
|
| + <paper-header-panel class="flex">
|
| + <paper-toolbar>
|
| + <div>Hello World!</div>
|
| + </paper-toolbar>
|
| + </paper-header-panel>
|
| +</body>
|
| +```
|
| +
|
| +Special support is provided for scrolling modes when one uses a `paper-toolbar` or equivalent for the header section. For example:
|
| +
|
| +```html
|
| +<paper-header-panel>
|
| + <paper-toolbar>Header</paper-toolbar>
|
| + <div>Content goes here...</div>
|
| +</paper-header-panel>
|
| +```
|
| +
|
| +If you want to use other than `paper-toolbar` for the header, add `paper-header` class to that
|
| +element:
|
| +
|
| +```html
|
| +<paper-header-panel>
|
| + <div class="paper-header">Header</div>
|
| + <div>Content goes here...</div>
|
| +</paper-header-panel>
|
| +```
|
| +
|
| +To have the content fit to the main area, use the `fit` class:
|
| +
|
| +```html
|
| +<paper-header-panel>
|
| + <div class="paper-header">standard</div>
|
| + <div class="content fit">content fits 100% below the header</div>
|
| +</paper-header-panel>
|
| +```
|
| +
|
| +### Mode
|
| +
|
| +Controls header and scrolling behavior. Options are `standard`, `seamed`, `waterfall`, `waterfall-tall`, `scroll` and
|
| +`cover`. Default is `standard`.
|
| +
|
| +Mode | Description
|
| +----------------|-------------
|
| +`standard` | The header is a step above the panel. The header will consume the panel at the point of entry, preventing it from passing through to the opposite side.
|
| +`seamed` | The header is presented as seamed with the panel.
|
| +`waterfall` | Similar to standard mode, but header is initially presented as seamed with panel, but then separates to form the step.
|
| +`waterfall-tall` | The header is initially taller (`tall` class is added to the header). As the user scrolls, the header separates (forming an edge) while condensing (`tall` class is removed from the header).
|
| +`scroll` | The header keeps its seam with the panel, and is pushed off screen.
|
| +`cover` | The panel covers the whole `paper-header-panel` including the header. This allows user to style the panel in such a way that the panel is partially covering the header.
|
| +
|
| +Example:
|
| +
|
| +```html
|
| +<paper-header-panel mode="waterfall">
|
| + <div class="paper-header">standard</div>
|
| + <div class="content fit">content fits 100% below the header</div>
|
| +</paper-header-panel>
|
| +```
|
| +
|
| +### Styling header panel:
|
| +
|
| +To change the shadow that shows up underneath the header:
|
| +
|
| +```css
|
| +paper-header-panel {
|
| + --paper-header-panel-shadow: {
|
| + height: 6px;
|
| + bottom: -6px;
|
| + box-shadow: inset 0px 5px 6px -3px rgba(0, 0, 0, 0.4);
|
| + };
|
| +}
|
| +```
|
| +
|
| +To change the panel container:
|
| +
|
| +```css
|
| +paper-slider {
|
| + --paper-header-panel-standard-container: {
|
| + border: 1px solid gray;
|
| + };
|
| +
|
| + --paper-header-panel-cover-container: {
|
| + border: 1px solid gray;
|
| + };
|
| +
|
| + --paper-header-panel-waterfall-container: {
|
| + border: 1px solid gray;
|
| + };
|
| +
|
| + --paper-header-panel-waterfall-tall-container: {
|
| + border: 1px solid gray;
|
| + };
|
| +}
|
| +```
