[![Published on NPM](https://img.shields.io/npm/v/@polymer/paper-scroll-header-panel.svg)](https://www.npmjs.com/package/@polymer/paper-scroll-header-panel) [![Build status](https://travis-ci.org/PolymerElements/paper-scroll-header-panel.svg?branch=master)](https://travis-ci.org/PolymerElements/paper-scroll-header-panel) [![Published on webcomponents.org](https://img.shields.io/badge/webcomponents.org-published-blue.svg)](https://webcomponents.org/element/@polymer/paper-scroll-header-panel) ## <paper-scroll-header-panel> **This element has been deprecated in favor of [app-layout](https://github.com/PolymerElements/app-layout).** `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. `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. ```css .paper-header { position: relative; } ``` ```html
