title: add title and description with LinkedIn share button
body: <p>I am using a simple JavaScript popup window to display a Share with LinkedIn dialog, based on the solution in this thread: <a href="https://stackoverflow.com/questions/10713542/how-to-make-custom-linkedin-share-button">How to make a custom LinkedIn share button</a>. </p>
  
  <pre><code>https://www.linkedin.com/cws/share?url=http%3A%2F%2Fgoogle.com
  </code></pre>
  
  <p>I was wondering if there is any way to add a title and description to the query string? I noticed that when you do this with the google example it automatically pulls in this information. Any help is appreciated.</p>
