title: How to change iframe src using css
body: <p>I am trying to remove ads from my profile on a website, so I don't have access to the original css or code, but there is still the ability to change the css code by editing the profile.</p>
  
  <p>For example I have added these lines: </p>
  
  <pre><code>&lt;style type="text/css"&gt; 
  .topad {display:none; visibility:hidden;}
  #buyers_ad {display:none; visibility:hidden;}
  &lt;/style&gt;
  </code></pre>
  
  <p>which removes an advertisement from the top and right side of the page.</p>
  
  <p>The problem is that there is an iframe that points to an advertisement. Is it possible to change the src that the iframe points to using css, but not html? The iframe does not have a class or id.</p>
  
  <p>It's an iframe inside a div, if that is helpful.</p>
