Pick a template and customize it: - **Getting started** ([Demo](https://polymerelements.github.io/app-layout/templates/getting-started) - [Source](/templates/getting-started)) - **Landing page** ([Demo](https://polymerelements.github.io/app-layout/templates/landing-page) - [Source](/templates/landing-page)) - **Publishing: Zuperkülblog** ([Demo](https://polymerelements.github.io/app-layout/templates/publishing) - [Source](/templates/publishing)) - **Shop: Shrine** ([Demo](https://polymerelements.github.io/app-layout/templates/shrine) - [Source](/templates/shrine)) - **Blog: Pesto** ([Demo](https://polymerelements.github.io/app-layout/templates/pesto) - [Source](/templates/pesto)) - **Scroll effects: Test drive** ([Demo](https://polymerelements.github.io/app-layout/templates/test-drive) - [Source](/templates/test-drive)) ### Patterns Sample code for various UI patterns: - **Transform navigation:** As more screen space is available, side navigation can transform into tabs. ([Demo](https://www.webcomponents.org/element/PolymerElements/app-layout/demo/patterns/transform-navigation/index.html) - [Source](/patterns/transform-navigation/x-app.html)) - **Expand Card:** Content cards may expand to take up more horizontal space. ([Demo](https://www.webcomponents.org/element/PolymerElements/app-layout/demo/patterns/expand-card/index.html) - [Source](/patterns/expand-card/index.html)) - **Material Design Responsive Toolbar:** Toolbar changes its height and padding to adapt mobile screen size. ([Demo](https://www.webcomponents.org/element/PolymerElements/app-layout/demo/patterns/md-responsive-toolbar/index.html) - [Source](/patterns/md-responsive-toolbar/index.html)) ## Users Here are some web apps built with App Layout: - [Youtube Web](https://www.youtube.com/new) - [Google I/O 2016](https://events.google.com/io2016/) - [Polymer project site](https://www.polymer-project.org/summit) - [Polymer summit](https://www.polymer-project.org/summit) - [Shop](https://shop.polymer-project.org) - [News](https://news.polymer-project.org) - [webcomponents.org](https://www.webcomponents.org/) - [Chrome Status](https://www.chromestatus.com/) - [Project Fi](https://fi.google.com/about/) - [NASA Open Source Software](https://code.nasa.gov/) See: [Documentation](https://www.webcomponents.org/element/@polymer/app-layout), [Demo](https://www.webcomponents.org/element/@polymer/app-layout/demo/demo/index.html). ## Usage ### Installation ``` npm install --save @polymer/app-layout ``` ### In an html file ```html

My app

``` ### In a Polymer 3 element ```js import {PolymerElement, html} from '@polymer/polymer'; import '@polymer/app-layout/app-layout.js'; class SampleElement extends PolymerElement { static get template() { return html`

My app

`; } } customElements.define('sample-element', SampleElement); ``` ## Contributing If you want to send a PR to this element, here are the instructions for running the tests and demo locally: ### Installation ```sh git clone https://github.com/PolymerElements/app-layout cd app-layout npm install npm install -g polymer-cli ``` ### Running the demo locally ```sh polymer serve --npm open http://127.0.0.1:/demo/ ``` ### Running the tests ```sh polymer test --npm ```
