最近在學習前端開發，發現許多酷炫的特效都離不開純CSS的幫助。在這里，我將向大家介紹一些純CSS特效的實現方法，供大家參考和學習。

1. 動態背景色漸變

.gradient {
background: linear-gradient(to right, #00C9FF , #92FE9D);
background-size: 200% 200%;
animation: gradientAnimation 2s ease infinite;
}
@keyframes gradientAnimation {
0% {
background-position: left;
}
100% {
background-position: right;
}
}

2. 懸浮放大效果

.hover-scale {
transition: transform .2s ease-in-out;
}
.hover-scale:hover {
transform: scale(1.2);
}

3. 3D卡片翻轉效果

.card-container {
perspective: 1000px;
}
.card {
position: relative;
transition: transform .6s;
transform-style: preserve-3d;
}
.card:hover {
transform: rotateY(180deg);
}
.card-front, .card-back {
position: absolute;
backface-visibility: hidden;
}
.card-front {
z-index: 2;
}
.card-back {
transform: rotateY(180deg);
}

4. 背景圖覆蓋文字效果

.overlay-text {
position: relative;
}
.overlay-text:before {
content: "";
position: absolute;
top: 0;
left: 0;
background: rgba(0,0,0,.5);
width: 100%;
height: 100%;
opacity: 0;
transition: opacity .2s ease-in-out;
}
.overlay-text:hover:before {
opacity: 1;
}

5. 動態水波效果

.wave {
transform-origin: center;
animation: waveAnimation 1.5s linear infinite;
}
@keyframes waveAnimation {
0% {
transform: translate(-50%, -50%) scale(1);
}
100% {
transform: translate(-50%, -50%) scale(1.5);
opacity: 0;
}
}

以上就是我分享的純CSS特效實現方法，希望能對大家有所幫助。
