title: Fire tag based on a div existing
body: <p>So I've got something that needs to fire on Wordpress blog pages, but there is nothing in the URL to help identify them.</p>
  
  <p>What does exist are content differences.</p>
  
  <p>Is there a way to fire a tag (or an event first and then fire off that event), based on the existence of a specific div?   for example only exists on the pages I want to fire the tag on.</p>
  
  <p>Any ideas?</p>
