Adding interactive features to images on a webpage can enhance user engagement and provide a unique browsing experience. In this tutorial, we’ll explore how to implement a zoom effect on an image as the user scrolls down the page using JavaScript. By the end of this guide, you’ll have a dynamic and visually appealing image zoom feature integrated into your website.

Step 1: Set Up the HTML Structure

<!DOCTYPE html>
<html lang="en">
  <!-- divinectorweb.com -->
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>zoom image on scroll</title>
    <link href="https://fonts.googleapis.com/css2?family=Merienda&display=swap" rel="stylesheet">
    <link href="https://fonts.googleapis.com/css2?family=Roboto&display=swap" rel="stylesheet">
    <link rel="stylesheet" href="style.css">
</head>
<body>

    <div class="zoom"><img src="image.jpg"></div>

    <div class="main-text">
        <h2>Main Text</h2>

    </div>  



    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
    <script>
        $(window).scroll(function() {
            var scroll = $(window).scrollTop()
            $(".zoom img").css({
                width: (100 + scroll / 5) + "%"
            })
        })
    </script>
</body>
</html>

Step 2: Style the Image Container

body {
    margin: 0;
    padding: 0;
}
div {
    width: 100%;
    height: 700px;
    overflow: hidden;
    position: relative;
}
div img {
    width: 100%;
    position: absolute;
    top: 0;
    left: 50%;
    transform: translate(-50%);
}
.main-text {
    text-align: center;
}
.main-text h2 {
    font-family: 'Merienda', cursive
    font-size: 40px;
}
.main-text p {
    font-size: 25px;
    font-family: 'Roboto', sans-serif;
    line-height: 35px;
}

Output 1:-

Output 2:- when you scroll
