Pure AngularJS component replicating Twitter Bootstrap's Affix component behavior. The affix behavior enables dynamic pinning of a DOM element during page scrolling when specific conditions are met.

• Install with bower, bower install angular-bootstrap-affix --save

• Or download the production version or the development version.

In your web page:

<script src="bower_components/angular/angular.js"></script>
<script src="bower_components/angular-jquery/dist/angular-jquery.min.js"></script>
<script src="bower_components/angular-bootstrap-affix/dist/angular-bootstrap-affix.min.js"></script>
<script src="scripts/app.js"></script>

In your app.js:

angular.module('myApp', ['mgcrea.bootstrap.affix'])

• To easily add affix behavior to any element, just add bs-affix to the element you want to spy on. Then use offsets to define when to toggle the pinning of an element on and off.

• Check Twitter Bootstrap's Affix docs.

<div class="iphone" bs-affix data-offset-top="200" data-offset-bottom="300">
  <div class="iphone-content">
  </div>
</div>
