Edit This Code :

<!DOCTYPE html>
<html>
<head>
<style>
.center { 
    height: 200px;
    position: relative;
    border: 3px solid green; 
}

.center p {
    margin: 0;
    position: absolute;
    top: 50%;
    left: 50%;
    -ms-transform: translate(-50%, -50%);
    transform: translate(-50%, -50%);
}
</style>
</head>
<body>

<h2>Centering</h2>
<p>In this example, we use positioning and the transform property to vertically and horizontally center the div element:</p>

<div class="center">
  <p>I am vertically and horizontally centered.</p>
</div>

<p>Note: The transform property is not supported in IE8 and earlier versions.</p>

</body>
</html>
