⚡ 动画性能优化

渲染层优化

/* 只使用 transform 和 opacity 进行动画 */
.optimized-animation {
  transform: translateX(0);
  opacity: 1;
  transition: transform 0.3s ease, opacity 0.3s ease;
}

.optimized-animation:hover {
  transform: translateX(10px);
  opacity: 0.8;
}

/* 避免触发布局和绘制的属性 */
.bad-animation {
  /* ❌ 会触发布局 */
  left: 100px;
  width: 200px;
  height: 200px;
  
  /* ❌ 会触发绘制 */
  background-color: red;
  border: 1px solid blue;
}

.good-animation {
  /* ✅ 只触发合成层 */
  transform: translateX(100px) scale(1.2);
  opacity: 0.8;
}

/* 使用 will-change 提示浏览器 */
.will-change {
  will-change: transform, opacity;
}

.will-change:hover {
  transform: scale(1.1);
}

/* 动画结束后移除 will-change */
.animation-complete {
  will-change: auto;
}

动画分层策略

/* 基础动画层 */
.animation-layer-1 {
  /* 背景层 - 静态 */
  background: linear-gradient(45deg, #ff6b6b, #4ecdc4);
}

.animation-layer-2 {
  /* 内容层 - 轻微动画 */
  transform: translateZ(0);
  transition: transform 0.3s ease;
}

.animation-layer-3 {
  /* 交互层 - 频繁动画 */
  transform: translateZ(0);
  will-change: transform;
  transition: transform 0.1s ease;
}

/* 复杂动画分层 */
.complex-animation {
  position: relative;
}

.complex-animation::before {
  content: '';
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background: rgba(255, 255, 255, 0.1);
  transform: translateX(-100%);
  transition: transform 0.6s ease;
}

.complex-animation:hover::before {
  transform: translateX(0);
}

动画性能监控

/* 性能友好的动画 */
.performance-optimized {
  /* 使用 transform 替代位置属性 */
  transform: translate3d(0, 0, 0);
  
  /* 使用 opacity 替代 visibility */
  opacity: 1;
  
  /* 避免在动画中改变布局属性 */
  /* 避免在动画中改变绘制属性 */
}

/* 动画性能测试 */
.performance-test {
  animation: performanceTest 1s ease-in-out infinite;
}

@keyframes performanceTest {
  0% {
    transform: translateX(0) scale(1);
    opacity: 1;
  }
  50% {
    transform: translateX(100px) scale(1.1);
    opacity: 0.8;
  }
  100% {
    transform: translateX(0) scale(1);
    opacity: 1;
  }
}

/* 使用 contain 属性优化 */
.contain-optimized {
  contain: layout style paint;
}

🎭 微交互设计
