13 `paper-scroll-header-panel` contains a header section and a content section. Th e

14 header is initially on the top part of the view but it scrolls away with the

15 rest of the scrollable content. Upon scrolling slightly up at any point, the

16 header scrolls back into view. This saves screen space and allows users to

17 access important controls by easily moving them back to the view.

18

19 __Important:__ The `paper-scroll-header-panel` will not display if its parent do es not have a height.

20

21 Using [layout attributes](http://www.polymer-project.org/docs/polymer/layout-att rs.html), you can easily make the `paper-scroll-header-panel` fill the screen

22

23 <body class="fullbleed layout vertical">

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

25 <paper-toolbar>

26 <div>Hello World!</div>

27 </paper-toolbar>

28 </paper-scroll-header-panel>

29 </body>

30

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

32

33 html, body {

34 height: 100%;

35 margin: 0;

36 }

37 paper-scroll-header-panel {

38 height: 100%;

39 }

40

41 `paper-scroll-header-panel` works well with `paper-toolbar` but can use any elem ent

42 that represents a header by adding a `paper-header` class to it.

43

44 <paper-scroll-header-panel>

45 <paper-toolbar>Header</paper-toolbar>

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

47 </paper-scroll-header-panel>

48

49 Styling scroll-header-panel:

50

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

52

53 paper-scroll-header-panel {

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

55 background-color: red;

56 };

57 }

58

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

60

61 paper-scroll-header-panel {

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

63 background-color: #f4b400;

64 };

65 }

66

67 @group Paper Element

68 @element paper-scrollheader-panel

69 @demo demo/index.html

70 @hero hero.svg
