title: ruby-on-rails: gravatar_for
body: <p>I was following the site <a href="http://railstutorial.org/" rel="nofollow">http://railstutorial.org/</a>
  and in the chapter 7, it shows an example of how to
  use gravatar_for.</p>
  
  <p>I tried to use it using</p>
  
  <pre><code>&lt;%= gravatar_for @user %&gt;
  </code></pre>
  
  <p>but it does not render correctly in my browser (firefox/opera/chrome)</p>
  
  <p>it render this html:</p>
  
  <pre><code>&lt;div&gt;classgravatartitleratingPGstylewidth:50px;height:50px;background:url(http://www.gravatar.com/avatar/bebfcf57d6d8277d806a9ef3385c078d?rating=PG&amp;amp;size=50) no-repeat;sslfalsealtdefault&lt;/div&gt; 
  </code></pre>
  
  <p>Could someone give me the solution for this problem? I got stuck and I really don't know to solve this. Thank very much.</p>
