Change color and background via negative index

Question

Aryan Kumar · Answer

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:
andlt;!DOCTYPE html>
andlt;html lang="en">
andlt;head>
  andlt;meta charset="UTF-8">
  andlt;meta name="viewport" content="width=device-width, initial-scale=1.0">
  andlt;title>Change Color and Background with jQueryandlt;/title>
  andlt;script src="https://code.jquery.com/jquery-3.6.4.min.js">andlt;/script>
andlt;/head>
andlt;body>
  andlt;p>This is the first paragraph.andlt;/p>
  andlt;p>This is the second paragraph.andlt;/p>
  andlt;p>This is the third paragraph.andlt;/p>
  andlt;p>This is the fourth paragraph.andlt;/p>
  andlt;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"
      });
    });
  andlt;/script>
andlt;/body>
andlt;/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.
