Animated Card Fan Effect with CSS | Interactive UI Design for Beginners

Creating interactive and animated layouts can dramatically improve how users engage with your website. In this tutorial, we’ll explore how to build a card fan animation effect using only HTML and CSS — no JavaScript required.

This effect creates a visual spread of cards when a user hovers over the container, and each card responds individually to mouse hover for extra interactivity.

What This Code Does

The project is built around four colored cards layered on top of each other. When the user hovers over the .main container, the cards spread apart like a fan, each rotating and shifting horizontally. On hovering over an individual card, that specific card rotates back to face forward, offering a crisp and clean spotlight effect.

How the Animation Works

1. Card Structure and Positioning

Each .card is absolutely positioned inside a .main container. This means all cards stack on top of one another until interacted with.

• .card elements have fixed size and a soft box shadow.

• Cards have unique background colors (black, blue, red, green) to distinguish them.

2. Hovering on Container

When the user hovers over the .main element:

• The cards shift left or right using translateX().

• They also rotate to simulate a fan-like spread using rotate().

3. Hovering on Individual Cards

Each card also has its own :hover state that:

• Cancels the initial rotation using rotate(0deg).

• Pulls the card out further, creating a focus effect.

• Uses !important to override the container hover styles.

This gives each card a chance to stand out when the user moves their mouse over it, enhancing interactivity.

Why This Effect Is Useful

This fan animation is ideal for:

• Showcasing product cards on e-commerce sites

• Presenting portfolio items creatively

• Interactive UI sections that require engagement

It’s lightweight, responsive, and perfect for users who are learning how to animate with CSS transitions and transforms.
