How to create mousemove parallax effects using HTML CSS & Javascript ?

Last Updated : 08 Jun, 2023

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.
