This is useful in creating popup text when mousing over an element on a page. Only one line of html is required!

popup_text

  $('body').on({
    mouseenter: function(e) { //the argument 'e' allows for the use of position tracking
      $('#popup_text').css({ //using the position of the current target (element which is moused over), we can position the popup text using CSS
         left:  $(this).offset().left-130,
         top:   $(this).offset().top-5
      });
    },
    mouseleave: function(e) { //once the mouse has left the target element, the CSS moves the popup text out of view
      $('#popup_text').css({
         left:  -9999,
      });
    }
  },', .top3star'); // ".top3star" was the element that we were interested in placing popup text near

//Example of html:
//<div id="popup_text">This is popup text!</div>
