Source Code Explanation

The heart of this design is the .inner container, which uses transform-style: preserve-3d and @keyframes to rotate all .card elements in 3D space. Each .card gets a unique rotation using the --index variable, giving it a perfect circular arrangement.

The perspective in CSS is applied to the .wrapper, creating the depth effect that makes the cards appear to pop out. A smooth radial gradient fills each card, and you can easily adjust transparency to learn how to make an image transparent or set a background image in CSS no repeat.

 

/* Card — each individual colored panel in the 3D carousel */
.card {
	position: absolute;
	width: var(--card-width);
	height: var(--card-height);
	border-radius: 12px;
	border: 2px solid;
	overflow: hidden;
	top: 0;
	left: 0;
	--index: 0;
	--color-r: 0;
	--color-g: 0;
	--color-b: 0;
	transform: 
	rotateY(calc((360deg / var(--cards-count)) * var(--index))) 
	translateZ(calc((var(--card-width) + var(--card-height))));
	border-color: rgb(var(--color-r), var(--color-g), var(--color-b));
}
/* Img — fills the card with a smooth radial gradient */
.img {
	width: 100%;
	height: 100%;
	background: radial-gradient(
	circle,
	rgba(var(--color-r), var(--color-g), var(--color-b), 0.2) 0%,
	rgba(var(--color-r), var(--color-g), var(--color-b), 0.6) 80%,
	rgba(var(--color-r), var(--color-g), var(--color-b), 0.9) 100%
	);
}
