In jQuery, you can use the `addClass` and `removeClass` methods to add and remove CSS classes from an element, respectively. Here's a simple example:```html<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width,...

In jQuery, you can use the `addClass` and `removeClass` methods to add and remove CSS classes from an element, respectively. Here's a simple example:

```html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Add/Remove CSS Classes with jQuery</title>
    <style>
        .highlight {
            color: red;
            font-weight: bold;
        }
    </style>
    <!-- Include jQuery -->
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
</head>
<body>

    <p id="myParagraph">This is a paragraph.</p>

    <button id="addClassBtn">Add Class</button>
    <button id="removeClassBtn">Remove Class</button>

    <script>
        // Wait for the document to be ready
        $(document).ready(function () {

            // Add class when the "Add Class" button is clicked
            $("#addClassBtn").click(function () {
                $("#myParagraph").addClass("highlight");
            });

            // Remove class when the "Remove Class" button is clicked
            $("#removeClassBtn").click(function () {
                $("#myParagraph").removeClass("highlight");
            });
        });
    </script>

</body>
</html>
```

In this example:

1. We have a paragraph element with the ID "myParagraph" and two buttons with IDs "addClassBtn" and "removeClassBtn."
2. In the `<style>` section, we define a CSS class named "highlight" with some styles.
3. We include the jQuery library from the CDN.
4. In the `<script>` section, we use jQuery to wait for the document to be ready (`$(document).ready(...)`) and then attach click event handlers to the "Add Class" and "Remove Class" buttons.
5. When the "Add Class" button is clicked, the `addClass` method is used to add the "highlight" class to the paragraph element.
6. When the "Remove Class" button is clicked, the `removeClass` method is used to remove the "highlight" class from the paragraph element.

Make sure to include the jQuery library in your project, either by downloading it and hosting it locally or by using a CDN (as shown in the example).
