Select any element and change its property via nth-child selector

Question

Aryan Kumar · Answer

Certainly! You can use the :nth-child selector to target a specific child element based on its position within its parent. Here's an example using jQuery to change the background color of the third child element of a container:
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 Property via nth-child Selectorandlt;/title>
  andlt;script src="https://code.jquery.com/jquery-3.6.4.min.js">andlt;/script>
  andlt;style>
    /* Optional: Some styling for better visibility */
    .container {
      display: flex;
      justify-content: space-around;
      margin-top: 20px;
    }
    .child {
      width: 50px;
      height: 50px;
      background-color: lightblue;
      display: flex;
      align-items: center;
      justify-content: center;
    }
  andlt;/style>
andlt;/head>
andlt;body>
andlt;div class="container">
  andlt;div class="child">1andlt;/div>
  andlt;div class="child">2andlt;/div>
  andlt;div class="child">3andlt;/div>
  andlt;div class="child">4andlt;/div>
  andlt;div class="child">5andlt;/div>
andlt;/div>
andlt;script>
  $(document).ready(function() {
    // Change the background color of the third child element
    $('.container .child:nth-child(3)').css('background-color', 'lightgreen');
  });
andlt;/script>
andlt;/body>
andlt;/html>
In this example:
The :nth-child(3) selector is used to target the third child element within the
.container.jQuery's css() method is then used to change the background color of the selected element.
You can customize the selector and the property changes based on your specific needs.
