How to Add and Remove Classes with jQuery

In jQuery, we can use addClass() and removeClass() methods to add and remove classes from an element. Here is a live example with code :

HTML
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Add and Remove Classes with jQuery</title>
  <link rel="stylesheet" href="styles.css">
  <script src="https://code.jquery.com/jquery-3.6.4.min.js"></script>
</head>
<body>
<div id="myElement">This is a div</div>

<button id="addClass">Add Class</button>
<button id="removeClass">Remove Class</button>

<script src="script.js"></script>
</body>
</html>
CSS
.highlight {
  background-color: yellow;
}
JavaScript
$(document).ready(function () {
  $("#addClass").on("click", function () {
    $("#myElement").addClass("highlight");
  });
  $("#removeClass").on("click", function () {
    $("#myElement").removeClass("highlight");
  });
});
