In jQuery, negative indices are not typically used to directly access elements or properties. However, you can achieve a similar effect by using the :last selector in combination with the prev() method. Let's say you want to change the color and background of the second-to-last paragraph. Here's an example:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Change Color and Background with jQuery</title>
  <script src="https://code.jquery.com/jquery-3.6.4.min.js"></script>
</head>
<body>

  <p>This is the first paragraph.</p>
  <p>This is the second paragraph.</p>
  <p>This is the third paragraph.</p>
  <p>This is the fourth paragraph.</p>

  <script>
    // Using jQuery to select the second-to-last paragraph
    $(document).ready(function(){
      // Selecting the second-to-last paragraph using :last and prev()
      $("p:last").prev().css({
        "color": "white",
        "background-color": "blue"
      });
    });
  </script>

</body>
</html>

In this example, $("p:last").prev() selects the second-to-last paragraph, and then the css method is used to change its color to white and background color to blue. Adjust the selectors and styles based on your specific needs.
