title: CSS show/hide next elements
body: <p>I'd like to hide the second <code>id</code> with value <code>my2</code> via CSS:</p>
  
  <pre><code>&lt;div class="node1"&gt;
    &lt;div class="xxx"&gt; blablabla &lt;/div&gt;
  &lt;/div&gt;
  &lt;div id="my2"&gt;
    &lt;div class="xxx"&gt; blablalbla &lt;/div&gt;
  &lt;/div&gt;
  &lt;div class="node2"&gt;
    &lt;div class="xxx"&gt; blablabla &lt;/div&gt;
  &lt;/div&gt;
  &lt;div id="my2"&gt;
    &lt;div class="xxx"&gt; blablalbla &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Is it possible as to hide the second <code>my2</code> <code>div</code>?</p>
  
  <p>E.g. </p>
  
  <pre><code>.node2 ? #my2 {
       display:none;
  }
  </code></pre>
  
  <p>Thank you!</p>
