In this article, we learn how to create moving elements based on the cursor.
Step 1: Create an element and apply CSS.
<!DOCTYPE html>
<html>
<head>
<title>
Create Moving Element
</title>
<style>
#myElement{
width: 10px;
height: 10px;
border-radius: 50px;
background-color: violet;
position: fixed;
}
</style>
</head>
<body>
<div id="myElement">
</div>
</body>
</html>
Step 2: Apply the below javascript to get cursor potion and apply position into created element.
var pointerX = -1;
var pointerY = -1;
document.onmousemove = function(event) {
pointerX = event.pageX;
pointerY = event.pageY;
pointer = document.querySelector('#myElement');
width = pointer.offsetWidth/2;
height = pointer.offsetHeight/2;
document.getElementById("myElement").style.top=(pointerY-height)+"px";
document.getElementById("myElement").style.left=(pointerX-width)+"px";
}
Step 3: Add “pointer-events: none;” CSS to make element unselectable.
#myElement{
pointer-events: none;
position: fixed;
width: 10px;
height: 10px;
border-radius: 50px;
background-color: violet;
}
Here is the full code:
<!DOCTYPE html>
<html>
<head>
<title>
Create Moving Element
</title>
<style>
#myElement{
pointer-events: none;
position: fixed;
width: 10px;
height: 10px;
border-radius: 50px;
background-color: violet;
}
</style>
</head>
<body>
<div id="myElement" style="">
</div>
<div class="test">
This is testing page.
</div>
</body>
<script>
var pointerX = -1;
var pointerY = -1;
document.onmousemove = function(event) {
pointerX = event.pageX;
pointerY = event.pageY;
pointer = document.querySelector('#myElement');
width = pointer.offsetWidth/2;
height = pointer.offsetHeight/2;
document.getElementById("myElement").style.top=(pointerY-height)+"px";
document.getElementById("myElement").style.left=(pointerX-width)+"px";
}
</script>
</html>
Here is the result:
Thanks.
