二、Grid创意布局

1. 杂志风格布局

.magazine-layout {
  display: grid;
  grid-template-columns: repeat(12, 1fr);
  grid-template-rows: auto;
  grid-gap: 20px;
}

.featured-article {
  grid-column: 1 / span 8;
  grid-row: 1 / span 3;
}

.secondary-article {
  grid-column: 9 / span 4;
  grid-row: 1 / span 1;
}

.tertiary-article {
  grid-column: span 4;
  grid-row: span 1;
}

@media (max-width: 768px) {
  .magazine-layout {
    grid-template-columns: 1fr;
  }
  
  .featured-article,
  .secondary-article,
  .tertiary-article {
    grid-column: 1;
    grid-row: auto;
  }
}

2. 动态网格画廊

.gallery {
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(250px, 1fr));
  grid-auto-rows: 200px;
  grid-gap: 15px;
  grid-auto-flow: dense;
}

.gallery-item {
  position: relative;
}

.gallery-item.wide {
  grid-column: span 2;
}

.gallery-item.tall {
  grid-row: span 2;
}

.gallery-item.large {
  grid-column: span 2;
  grid-row: span 2;
}

三、响应式设计进阶

1. 容器查询应用

.card {
  container-type: inline-size;
}

@container (min-width: 400px) {
  .card-content {
    display: flex;
    gap: 20px;
  }
  
  .card-image {
    flex: 0 0 150px;
  }
}

@container (max-width: 399px) {
  .card-image {
    width: 100%;
    margin-bottom: 15px;
  }
}

2. 响应式排版

:root {
  --base-font-size: 16px;
  --type-scale: 1.2;
  
  --h1: calc(var(--h2) * var(--type-scale));
  --h2: calc(var(--h3) * var(--type-scale));
  --h3: calc(var(--h4) * var(--type-scale));
  --h4: calc(var(--body) * var(--type-scale));
  --body: var(--base-font-size);
}

@media (min-width: 768px) {
  :root {
    --type-scale: 1.25;
  }
}

@media (min-width: 1200px) {
  :root {
    --type-scale: 1.333;
  }
}

h1 { font-size: var(--h1); }
h2 { font-size: var(--h2); }
h3 { font-size: var(--h3); }
p { font-size: var(--body); }

四、3D交互效果

1. 3D卡片翻转

.flip-card {
  perspective: 1000px;
}

.flip-card-inner {
  transition: transform 0.8s;
  transform-style: preserve-3d;
}

.flip-card:hover .flip-card-inner {
  transform: rotateY(180deg);
}

.flip-card-front,
.flip-card-back {
  backface-visibility: hidden;
  position: absolute;
  width: 100%;
  height: 100%;
}

.flip-card-back {
  transform: rotateY(180deg);
}

2. 3D视差效果

.parallax-container {
  perspective: 1px;
  height: 100vh;
  overflow-x: hidden;
  overflow-y: auto;
}

.parallax-layer {
  position: absolute;
  transform-origin: center;
}

.layer-1 {
  transform: translateZ(-3px) scale(4);
}

.layer-2 {
  transform: translateZ(-1px) scale(2);
}

.layer-3 {
  transform: translateZ(0);
}

五、滚动驱动动画

1. 基于滚动位置的动画

@keyframes fade-in {
  from { opacity: 0; transform: translateY(50px); }
  to { opacity: 1; transform: translateY(0); }
}

.scroll-animated {
  animation: fade-in linear;
  animation-timeline: view();
  animation-range: entry 0% entry 100%;
}

2. 横向滚动动画

.horizontal-scroll {
  scroll-timeline: --horizontal-scroll inline;
  overflow-x: scroll;
  white-space: nowrap;
}

.horizontal-item {
  animation: slide-in linear;
  animation-timeline: --horizontal-scroll;
  animation-range: entry 0% cover 50%;
}

@keyframes slide-in {
  from { transform: translateX(100%); }
  to { transform: translateX(0); }
}

六、创意视觉效果

1. 动态渐变文字

.gradient-text {
  background: linear-gradient(
    90deg,
    #ff5e7d,
    #5e72eb,
    #00d2ff,
    #ff5e7d
  );
  background-size: 300% auto;
  color: transparent;
  -webkit-background-clip: text;
  background-clip: text;
  animation: gradient-flow 5s linear infinite;
}

@keyframes gradient-flow {
  to { background-position: 300% center; }
}

2. 裁剪路径动画

.morph-shape {
  clip-path: polygon(
    50% 0%, 100% 50%, 50% 100%, 0% 50%
  );
  transition: clip-path 0.6s ease;
}

.morph-shape:hover {
  clip-path: polygon(
    30% 0%, 70% 0%, 100% 30%, 100% 70%, 70% 100%, 30% 100%, 0% 70%, 0% 30%
  );
}

七、性能优化策略

1. 硬件加速优化

.optimized-animation {
  transform: translate3d(0, 0, 0);
  will-change: transform, opacity;
  backface-visibility: hidden;
}

/* 避免过度使用will-change */
.animated-element {
  will-change: transform;
  transition: transform 0.3s ease;
}

2. 分层渲染控制

.performance-layer {
  contain: paint layout style;
  content-visibility: auto;
}

/* 关键动画元素 */
.animated-element {
  isolation: isolate;
  transform: translateZ(0);
}
