title: Spin or rotate an image on hover
body: <p>I want to find out how to make a <strong>spinning or rotating image</strong> when it is hovered. I would like to know how to emulate that functionality with <em>CSS</em> on the following code :</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>img {
    border-radius: 50%;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;img src="http://i.imgur.com/3DWAbmN.jpg" /&gt;</code></pre>
  </div>
  </div>
  </p>
