[![Build status](https://travis-ci.org/PolymerElements/paper-behaviors.svg?branch=master)](https://travis-ci.org/PolymerElements/paper-behaviors) _[Demo and API docs](https://elements.polymer-project.org/elements/paper-behaviors)_ ##Polymer.PaperCheckedElementBehavior Use `Polymer.PaperCheckedElementBehavior` to implement a custom element that has a `checked` property similar to `Polymer.IronCheckedElementBehavior` and is compatible with having a ripple effect. ##Polymer.PaperInkyFocusBehavior `Polymer.PaperInkyFocusBehavior` implements a ripple when the element has keyboard focus. ##Polymer.PaperRippleBehavior `Polymer.PaperRippleBehavior` dynamically implements a ripple when the element has focus via pointer or keyboard. NOTE: This behavior is intended to be used in conjunction with and after `Polymer.IronButtonState` and `Polymer.IronControlState`.
