How can I style an IFRAME element that has a constantly changing class name? [closed]
You can select every iframe, just by writing: iframe{display:none} If you have multiple iframes, and this is the only one you want to apply this styling to, you can write something like this: iframe[src^=”//assets.pinterest.com/pidget.html”]{display:none} Note: Not really a WordPress question, but pure CSS related.
