在網頁設計領域中，使用純CSS進行動畫效果的設計已經成爲了一種流行的趨勢。本文將介紹28個炫酷的純CSS特效動畫示例，並且提供每個例子的源代碼，以幫助讀者理解和實現這些效果。以下就是這28個例子及其對應的源碼：
1. 旋轉立方體
@keyframes rotate {
0%, 100% { transform: perspective(600px) rotateY(0deg); }
50% { transform: perspective(600px) rotateY(-90deg); }
}
.cube {
width: 100px;
height: 100px;
position: relative;
transform-style: preserve-3d;
animation: rotate 4s infinite linear both;
}
.cube div {
position: absolute;
top: 0; left: 0; right: 0; bottom: 0;
background-color: #4CAF50;
border-radius: 10px;
box-shadow: inset 0 0 10px rgba(0, 0, 0, 0.2);
}
.front { transform: translateZ(50px); }
.back { transform: rotateY(180deg) translateZ(50px); }
.left { transform: rotateY(-90deg) translateZ(50px); }
.right { transform: rotateY(90deg) translateZ(50px); }
