title: css styling based on another elements class?
body: <p>Is it possible to do this without JS and how would I write it?  If the <code>.content-pto.active</code> then I want to change the <code>span.ico</code> to animate....</p>
  
  <pre><code>&lt;div id="pto-button"&gt;
      &lt;div&gt;
          &lt;div class="title-pto"&gt;
            &lt;div&gt;content&lt;span class="ico"&gt;&lt;/span&gt;&lt;/div&gt;
          &lt;/div&gt;
          &lt;div class="content-pto active"&gt;
              &lt;p&gt;more content&lt;/p&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
