Your code adds and removes the classes and the “highlighted” styling is applied, but immediately after that the page reloads and the original styling is rendered. The reloading is the default behavior and you can suppress it by adding event.preventDefault();:

  $(document).on('click', 'ul li', function (event) {
    event.preventDefault();
    $(this).addClass('active').siblings().removeClass('active')
  })

You can read more about it here: https://www.geeksforgeeks.org/jquery-event-preventdefault-method/

PS: Posting a live demo that recreates an issue on something like jsfiddle, codepen etc. is generally helpful …
