title: adding a css inside a link_to do function
body: <p>I'm trying to make link_to function have a css class attached to it,</p>
  
  <p>My code is something like this:</p>
  
  <pre><code>&lt;%= link_to newGame do%&gt;
  &lt;%= image_tag newGame.image_url.to_s %&gt;
  &lt;% end %&gt;
  </code></pre>
  
  <p>which links an image to its content, but I need to add a class="thumbnail" to the link, </p>
  
  <p>ie:</p>
  
  <pre><code>&lt;a href="/games/:id" class="thumbnaill&gt;
  </code></pre>
  
  <p>instead of what its currently generating:</p>
  
  <pre><code>&lt;a href="/games/:id"&gt;
  </code></pre>
  
  <p>Thanks</p>
