Material design: Scrolling techniques
paper-scroll-header-panel contains a header section and a content section. The
header is initially on the top part of the view but it scrolls away with the
rest of the scrollable content. Upon scrolling slightly up at any point, the
header scrolls back into view. This saves screen space and allows users to
access important controls by easily moving them back to the view.
Important: The paper-scroll-header-panel will not display if its parent does not have a height.
Using layout classes or custom properties, you can easily make the paper-scroll-header-panel fill the screen
<body class="fullbleed layout vertical">
<paper-scroll-header-panel class="flex">
<paper-toolbar>
<div>Hello World!</div>
</paper-toolbar>
</paper-scroll-header-panel>
</body>or, if you would prefer to do it in CSS, just give html, body, and paper-scroll-header-panel a height of 100%:
html, body {
height: 100%;
margin: 0;
}
paper-scroll-header-panel {
height: 100%;
}paper-scroll-header-panel works well with paper-toolbar but can use any element
that represents a header by adding a paper-header class to it.
Note: If the class paper-header is used, the header must be positioned relative or absolute. e.g.
.paper-header {
position: relative;
}<paper-scroll-header-panel>
<div class="paper-header">Header</div>
<div>Content goes here...</div>
