##<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, you can make the paper-header-panel fill the screen
<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.
Example:
<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.
Example:
<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.
<paper-header-panel>
<div class="paper-header">standard</div>
<div class="fit">content fits 100% below the header</div>
</paper-header-panel>
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:
<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>
To change the shadow that shows up underneath the header:
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 in different modes:
paper-header-panel {
--paper-header-panel-standard-container: {
border: 1px solid gray;
};
--paper-header-panel-seamed-container: {
border: 1px solid gray;
};
--paper-header-panel-waterfall-container: {
border: 1px solid gray;
};
--paper-header-panel-waterfall-tall-container: {
border: 1px solid gray;
};
--paper-header-panel-scroll-container: {
border: 1px solid gray;
};
--paper-header-panel-cover-container: {
border: 1px solid gray;
};
}
