title: Facebook share button with custom title and message etc
body: <p>I have integrated a Facebook Share button in my website. The one that you can generate here:</p>
  
  <p><a href="https://developers.facebook.com/docs/plugins/share-button/" rel="nofollow">https://developers.facebook.com/docs/plugins/share-button/</a></p>
  
  <p>But how can I tell it what title, message to show and what url to redirect to? It now all "tries" to automatically resolve this from the web page.</p>
  
  <p>It uses the right title from the <code>&lt;title&gt;</code> tag. But the meta <code>description</code> tag is not working. And I also have no clue how to set a custom URL and image.</p>
  
  <p>All I have now is:</p>
  
  <p>This right below the opening of the <code>body</code> tag:</p>
  
  <pre><code>&lt;div id="fb-root"&gt;&lt;/div&gt;
  &lt;script&gt;(function(d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0];
    if (d.getElementById(id)) return;
    js = d.createElement(s); js.id = id;
    js.src = "//connect.facebook.net/nl_NL/sdk.js#xfbml=1&amp;appId=19158xxxxxxxxx&amp;version=v2.0";
    fjs.parentNode.insertBefore(js, fjs);
  }(document, 'script', 'facebook-jssdk'));&lt;/script&gt;
  </code></pre>
  
  <p>And this on a product detail page:</p>
  
  <pre><code>&lt;div class="fb-share-button" data-type="button_count"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>How can I customize everything here?</p>
