You can use this information to change styles and/or attributes depending on it. ## Installation ```sh $ bower install --save daKmoR/grain-responsive-behavior ``` ## Getting Started Import the package. ```html ``` Create your element using this behavior. You can now access is-mobile, is-tablet, is-desktop. ```js class GrainResponsiveBehaviorExample extends GrainResponsiveBehavior(Polymer.Element) { // your code } ``` If you wish to have an responsive attribute you should create 3 attributes foo, mobileFoo, tabletFoo and init the Behavior with `this.initResponsiveBehaviorFor('foo'); ```js class GrainResponsiveBehaviorExample extends GrainResponsiveBehavior(Polymer.Element) { static get is() { return 'grain-responsive-behavior-example' } static get properties() { return { marked: { type: String, reflectToAttribute: true, value: 'false', // 'true', 'false' }, mobileMarked: { type: String, reflectToAttribute: true }, tabletMarked: { type: String, reflectToAttribute: true }, }; } constructor() { super(); this.initResponsiveBehaviorFor('marked'); } } ``` *For more information, see the API documentation.* ## Working on the Element First, make sure you have the [Polymer CLI](https://www.npmjs.com/package/polymer-cli) installed. * View the Element via `polymer serve` * Run tests via `polymer test`
