How to create mousemove parallax effects using HTML CSS & Javascript ?
In this article, we will learn to create a Mousemove parallax effect using CSS and JavaScript. In the Mousemove parallax effect, an image moves in a different direction at a different speed when we move the cursor. Parallax effects are used to make the website more attractive and increase the interactivity level of the website. The parallax effect is a way to scroll or move the foreground & background images at different speeds in different directions. We can use either of the combination ie, a text with an image or an image with an image, to create the parallax effect.
Approach:
- In the <body> tag, create a <div> tag to assign some images on which the parallax effect is to be applied, and assign a class name and value attribute to each image that is responsible for the amount of shifting of the image.
- For the CSS stylings, add some CSS properties in the style tag such as position and size of images.
- We have taken the help of JavaScript to implement the parallax effect. In the snippet given under the script tag, we have created a function parallax that uses the class name of the img tag to get the value for positioning and shifting purposes.
Example: In this step, we will create a movemouse parallax effect using the above approach.

class="mouse" value="-5" />
</div>
<script type="text/javascript">
document.addEventListener("mousemove", parallax);
function parallax(event) {
this.querySelectorAll(".mouse").forEach((shift) => {
const position = shift.getAttribute("value");
const x = (window.innerWidth - event.pageX * position) / 90;
const y = (window.innerHeight - event.pageY * position) / 90;
shift.style.transform = `translateX(${x}px) translateY(${y}px)`;
});
}
</script>
</body>
</html>
Output:
From the above example, you can see that when we move the cursor from one direction to another the images start floating or shifting.
