Hide all "about the x category" topics

This is an update that works perfectly for my use case.

If you want to hide a particular topic via CSS, on page load and henceforth, this will do it. Just add your topic IDs to the list of topic IDs:

<script>
  document.addEventListener("DOMContentLoaded", function() {
    var topicIdsToHide = ["10", "20", "30"]; // Add your topic IDs here

    function hideElementsByDataTopicIds() {
      topicIdsToHide.forEach(function(id) {
        var element = document.querySelector('[data-topic-id="' + id + '"]');
        if (element) {
          element.style.display = 'none';
        }
      });
    }

    // Run the function initially
    hideElementsByDataTopicIds();

    // Create a mutation observer to monitor DOM changes
    var observer = new MutationObserver(function(mutations) {
      mutations.forEach(function(mutation) {
        hideElementsByDataTopicIds();
      });
    });

    // Observe the entire document
    observer.observe(document.body, { childList: true, subtree: true });
  });
</script>
