      I almost missed this part. In the same way, by using the CSS
      Inspector, you can identify the offending rules and write your own
      rules to override them. For your needs, it might be easier to keep
      your rule on the <tt>:after</tt> (like you did) and just reset
      everything the other rules are contributing on the <tt>:before</tt>
      :</p>
    <p><tt><br>
      </tt><tt>map > topicmeta > data-about >
        data[name="icon_url"]:after {</tt><tt><br>
      </tt><tt>     content: "Pick a local icon or a remote URL for the
