title: Hide text node in element, but not children
body: <p>I'm having a little trouble with CSS and can't seem to find a solution. I have this HTML</p>
  
  <pre><code>&lt;div id="closelink"&gt;
    &lt;a href=""&gt;Close&lt;/a&gt;
    Click to close
  &lt;/div&gt;
  </code></pre>
  
  <p>Now I want to hide the text «Click to close» only, without hiding neither the div, nor the link within it.</p>
  
  <p>Can this be done?</p>
