I added this code now:

add_action('wp_footer', function () {
    ?>
    <script>
    document.addEventListener("DOMContentLoaded", function () {
      const tocLinks = document.querySelectorAll('.avia-toc-link');
      const headingSelectors = document.querySelector('.avia-toc-container').dataset.level.split(',');
      const headings = Array.from(document.querySelectorAll(headingSelectors.join(',')));

      tocLinks.forEach(link => {
        link.addEventListener('click', function () {
          tocLinks.forEach(l => l.classList.remove('active'));
          this.classList.add('active');
        });
      });

      function onScroll() {
        let scrollPosition = window.scrollY + 100;
        let currentId = null;

        for (let i = headings.length - 1; i >= 0; i--) {
          const heading = headings[i];
          if (heading.offsetTop <= scrollPosition) {
            currentId = heading.id;
            break;
          }
        }

        if (currentId) {
          tocLinks.forEach(link => {
            link.classList.toggle('active', link.getAttribute('href') === '#' + currentId);
          });
        }
      }

      window.addEventListener('scroll', onScroll);
      onScroll();
    });
    </script>
    <?php
}, 9999);

but a can’t see any change in the behaviour.

I added both codes but I can’t see any change on the blog Post.
Is this correct ?
wp_footer
since it is the sidebar, not the footer?

How can I change the font color and ensure that not only capital letters are used?

Everything works now. Thank you!

Thank you Ismail!

I tested it. Now I receive the date but also the author and the tags. Is it possible to just show the date?

Ok, I’ll have a look at it. Thank you.

Thank you

Thank you for your reply.

If I would do it manualy: Is there a way to put the Page Content element in a Layout Element (for example 1/5)?
Or ist there any other way to have a Page Content on the right column of the page?
