title: Rails: browser can't scroll
body: <p>I use <code>embedly</code> card to display my content. After it call its <code>javascript</code> file, it will change link into a <code>embedly</code> card.</p>
  
  <p>I have deployed into <code>heroku</code> 
  <a href="https://intelligent-madame-5204.herokuapp.com/" rel="nofollow">https://intelligent-madame-5204.herokuapp.com/</a></p>
  
  <p>However, after it become a embedly card, I can't use mouse to scroll down. </p>
  
  <p>I put this javascript in <strong>application.js</strong></p>
  
  <pre><code>(function(w, d){
     var id='embedly-platform', n = 'script';
     if (!d.getElementById(id)){
       w.embedly = w.embedly || function() {(w.embedly.q = w.embedly.q || []).push(arguments);};
       var e = d.createElement(n); e.id = id; e.async=1;
       e.src = ('https:' === document.location.protocol ? 'https' : 'http') + '://cdn.embedly.com/widgets/platform.js';
       var s = d.getElementsByTagName(n)[0];
       s.parentNode.insertBefore(e, s);
     }
    })(window, document);
  </code></pre>
  
  <p>And I put link like this way in <strong>index.html.erb</strong></p>
  
  <pre><code>&lt;%= link_to "Learn More",posts.content, class: "embedly-card" %&gt;
  </code></pre>
