Đoạn mã JavaScript này tuy không sử dụng thẻ MARQUEE nhưng lại hoạt động tương tự như thẻ này, nghĩa là bạn có thể làm cho một đoạn nội dung nào đó di chuyển liên tục theo bốn hướng, khi người dùng rê chuột vào thì ngừng di chuyển,... Với mã này, hầu như bạn chỉ dùng JavaScript để cài đặt một "MARQUEE".
