CSS摩天輪是一種具有視覺沖擊力的網頁特效，可以通過CSS代碼實現。下面是一份基本的CSS摩天輪代碼樣例。

<div class="wheel">
<div class="wrapper">
<div class="item item-1"></div>
<div class="item item-2"></div>
<div class="item item-3"></div>
<div class="item item-4"></div>
<div class="item item-5"></div>
<div class="item item-6"></div>
<div class="item item-7"></div>
<div class="item item-8"></div>
<div class="item item-9"></div>
</div>
</div>
<style>
.wheel {
height: 300px;
width: 300px;
position: relative;
margin: 0 auto;
transform: rotate(45deg);
}
.wrapper {
height: 100%;
width: 100%;
position: absolute;
top: 0;
left: 0;
animation: spin 15s linear infinite;
transform-style: preserve-3d;
animation-play-state: paused;
}
.item {
height: 50%;
width: 50%;
position: absolute;
top: 0;
left: 0;
transform-style: preserve-3d;
}
.item-1 {
background-color: #ffa7c4;
transform: translateZ(150px);
}
.item-2 {
background-color: #ffdef3;
transform: rotateY(40deg) translateZ(150px);
}
.item-3 {
background-color: #fcf6b8;
transform: rotateY(80deg) translateZ(150px);
}
.item-4 {
background-color: #88d8b0;
transform: rotateY(120deg) translateZ(150px);
}
.item-5 {
background-color: #57c8f2;
transform: rotateY(160deg) translateZ(150px);
}
.item-6 {
background-color: #d19feb;
transform: rotateY(200deg) translateZ(150px);
}
.item-7 {
background-color: #fcd8a9;
transform: rotateY(240deg) translateZ(150px);
}
.item-8 {
background-color: #afcedc;
transform: rotateY(280deg) translateZ(150px);
}
.item-9 {
background-color: #b0c4d9;
transform: rotateY(320deg) translateZ(150px);
}
@keyframes spin {
from {
transform: rotateY(0deg);
}
to {
transform: rotateY(360deg);
}
}
.wheel:hover .wrapper {
animation-play-state: running;
}
</style>

上述代碼中，使用了transform屬性來實現3D效果，同時利用了CSS動畫和動態變化，讓摩天輪輪廓得以明顯展示。
