How to create a moving div using JavaScript ?

In this article, we will learn to create a moving HTML div using JavaScript. The div will move left to right using HTML, CSS, and JavaScript

Approach:

  • We have to create an HTML div and add some CSS to the div using a glass ball.
  •  In CSS, we add some background-color to the body and give some height, width, and color to the div.
  • Now we will add margin-left to the div using JavaScript. So it will move left to right.
  • In JavaScript, we grab the div using the id name. And after some interval of time, we will add margin-left to the div.

Example: In this example, we are using the above-explained approach.

HTML




<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8" />
    <meta http-equiv="X-UA-Compatible"
          content="IE=edge" />
    <meta name="viewport"
          content="width=device-width,
                   initial-scale=1.0" />
    <style>
        body {
            background-color: aqua;
            display: flex;
            align-items: center;
        }
 
        .ball {
            height: 12rem;
            width: 12rem;
            background-color: white;
            border-radius: 50%;
            margin-top: 20rem;
        }
    </style>
</head>
<body>
    <div class="container">
        <div class="ball"
             id="ballID"></div>
    </div>
    <script>
        let ball = document.getElementById("ballID");
 
        var myVar = setInterval(spostaDiv, 90);
        var margin = 0;
 
        let l = window.screen.width;
        let w = 1300;
 
        function spostaDiv() {
            console.log(w);
            if (margin == w) {
                margin = 0 + "px";
            } else {
                ball.style.marginLeft = margin + "px";
            }
            margin += 10;
        }
    </script>
</body>
</html>
