title: change link color, adjust font size and remove "powered by" links inside cross-domain iframe
body: <p>I wish to change link color, adjust font size and even completely remove it. If you may, please visit the tawk.to website and in the lower right corner you'll see the link back that resides inside of iframe(s).</p>
  
  <pre><code>&lt;div id="bottomContainer"&gt;&lt;a id="tawktoLink" href="javascript:void(0);" tabindex="-1"&gt;©&amp;nbsp;tawk.to&lt;/a&gt;&lt;/div&gt;
  </code></pre>
  
  <p>I tried using CSS but that failed misserably and even attempted using a small script like:</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
  $(document).ready(function() {
      ('#tawkchat-iframe-container').contents().find('#bottomContainer').hide();
  });
  &lt;/script&gt;
  </code></pre>
  
  <p>Many live chat services display a link, specifically, apps like:</p>
  
  <ul>
  <li>1click</li>
  <li>bubbles</li>
  <li>clickdesk</li>
  <li>live2support</li>
  <li>heybubble</li>
  <li>intercom</li>
  <li>liveagen</li>
  <li>livechat</li>
  <li>livezilla</li>
  <li>olar</li>
  <li>zopim</li>
  <li>tawk.to</li>
  </ul>
