##<paper-scroll-header-panel>

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.

<paper-scroll-header-panel>
  <paper-toolbar>Header</paper-toolbar>
  <div>Content goes here...</div>
</paper-scroll-header-panel>
