	1 paper-scroll-header-panel

	2 ========================

	3

	4 `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 re st of the scrollable content. Upon scrolling slightly up at any point, the heade r scrolls back into view. This saves screen space and allows users to access imp ortant controls by easily moving them back to the view.

	5

	6 Important: The `paper-scroll-header-panel` will not display if its parent does n ot have a height. Using layout classes, you can easily make the `paper-scroll-he ader-panel` fill the screen

	7

	8 ```html

	9 <body class="fullbleed layout vertical">

	10 <paper-scroll-header-panel class="flex">

	11 <paper-toolbar>

	12 Hello World!

	13 </paper-toolbar>

	14 </paper-scroll-header-panel>

	15 </body>

	16 ```

	17 or, if you would prefer to do it in CSS, just give html, body, and `paper-scroll -header-panel` a height of 100%:

	18 ```css

	19 html, body {

	20 height: 100%;

	21 margin: 0;

	22 }

	23 paper-scroll-header-panel {

	24 height: 100%;

	25 }

	26 ```

	27 `paper-scroll-header-panel` works well with `paper-toolbar` but can use any elem ent that represents a header by adding a core-header class to it.

	28

	29 ```html

	30 <paper-scroll-header-panel>

	31 <paper-toolbar>Header</paper-toolbar>

	32 <div>Content goes here...</div>

	33 </paper-scroll-header-panel>

	34 ```

	35

	36 ### Styling scroll-header-panel:

	37

	38 To change background for toolbar when it is at its full size:

	39

	40 ```css

	41 paper-scroll-header-panel {

	42 --paper-scroll-header-panel-full-header: {

	43 background-color: red;

	44 };

	45 }

	46 ```

	47

	48 To change the background for toolbar when it is condensed:

	49

	50 ```css

	51 paper-scroll-header-panel {

	52 --paper-scroll-header-panel-condensed-header: {

	53 background-color: #f4b400;

	54 };

	55 }

	56 ```
