<body>
    <div class="box"></div>

    <script>
       
<script>
    // Wait for the DOM to be ready
    document.addEventListener("DOMContentLoaded", function() {
        // GSAP animation
        gsap.to(".box", {
            x: 200,
            backgroundColor: "blue",
            duration: 1, // Animation duration in seconds
            scrollTrigger: {
                trigger: ".box", // Element that triggers the animation
                start: "top center", // Animation starts when this point of the element is at the top center of the viewport
                end: "bottom center", // Animation ends when this point of the element is at the bottom center of the viewport
                scrub: true, // Smoothly scrubs the animation as you scroll
            },
        });
    });
</script>
