HTML5现代魔法：构建动态3D卡片悬停交互系统

一、设计原理

基于CSS transform-style和perspective的3D引擎，实现60fps流畅的卡片悬停效果

二、核心实现

1. 3D卡片基础结构

<div class="card-container">
    <div class="card">
        <div class="card-face front">
            <h3>正面内容</h3>
        </div>
        <div class="card-face back">
            <p>背面内容</p>
        </div>
    </div>
</div>

<style>
.card-container {
    perspective: 1000px;
    width: 300px;
    height: 400px;
}

.card {
    position: relative;
    width: 100%;
    height: 100%;
    transform-style: preserve-3d;
    transition: transform var(--transition-speed);
}

.card-face {
    position: absolute;
    width: 100%;
    height: 100%;
    backface-visibility: hidden;
    border-radius: 16px;
    box-shadow: 0 8px 24px var(--shadow-color);
}

.front {
    background: white;
}

.back {
    background: var(--primary-color);
    transform: rotateY(180deg);
    color: white;
}
</style>

2. 悬停交互逻辑

<script>
document.querySelectorAll('.card').forEach(card => {
    card.addEventListener('mousemove', (e) => {
        const rect = card.getBoundingClientRect();
        const x = e.clientX - rect.left;
        const y = e.clientY - rect.top;
        
        const centerX = rect.width / 2;
        const centerY = rect.height / 2;
        
        const rotateY = (x - centerX) / 20;
        const rotateX = (centerY - y) / 10;
        
        card.style.transform = `rotateX(${rotateX}deg) rotateY(${rotateY}deg)`;
    });
    
    card.addEventListener('mouseleave', () => {
        card.style.transform = 'rotateX(0) rotateY(0)';
    });
});
</script>

三、高级特性

1. 动态光影效果

.card::after {
    content: '';
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    border-radius: 16px;
    background: radial-gradient(
        circle at var(--mouse-x) var(--mouse-y),
        rgba(255,255,255,0.8) 0%,
        rgba(255,255,255,0) 70%
    );
    opacity: 0;
    transition: opacity 0.3s;
}

.card:hover::after {
    opacity: 0.6;
}

// JS更新鼠标位置
card.addEventListener('mousemove', (e) => {
    card.style.setProperty('--mouse-x', `${e.offsetX}px`);
    card.style.setProperty('--mouse-y', `${e.offsetY}px`);
});

2. 性能优化方案

.card {
    will-change: transform;
    transform: translateZ(0); /* 触发硬件加速 */
}

/* 减少低端设备动画 */
@media (prefers-reduced-motion: reduce) {
    .card {
        transition: none;
    }
}

/* 移动端触摸支持 */
.card {
    touch-action: none;
}
