Parallax effect is a popular technique used in website and mobile UI design that creates an illusion of depth by making the background move at a slower rate than the foreground. This technique can add a dynamic and interactive element to a design, but it also has its own set of advantages and disadvantages that should be considered before implementing it.

In this article, we will explore the parallax effect and its impact on website and mobile UI design, its advantages and disadvantages, and some best practices to follow when using this technique.

What is Parallax Effect?

The parallax effect, also known as parallax scrolling, is a technique that creates a 3D effect by moving the background at a slower rate than the foreground. This effect is achieved by positioning multiple layers of images or graphics on top of each other and animating them at different speeds.

The parallax effect was first introduced in video games, where it was used to create the illusion of depth and movement. In recent years, it has become a popular technique in website and mobile UI design to create a dynamic and interactive user experience.
