创作背景

刚看到csdn出活动了，赶时间，直接上代码。

html结构

  <div class="cloud-bg">
    <div class="fog"></div>
    <div class="fog"></div>
  </div>

css样式

body {
  margin: 0;
  min-height: 100vh;
}

.cloud-bg {
  position: relative;
  height: 100vh;
  background: radial-gradient(circle at bottom, #6D8EA0, #3A506B);
  overflow: hidden;
}

.fog {
  position: absolute;
  width: 200%;
  height: 200%;
  background: 
    linear-gradient(90deg, 
      rgba(255,255,255,0) 10%,
      rgba(255,255,255,0.2) 50%,
      rgba(255,255,255,0) 90%
    );
  filter: blur(40px);
  animation: drift 30s linear infinite;
}

@keyframes drift {
  0% { transform: translate(-50%, -50%) rotate(15deg); }
  100% { transform: translate(50%, 50%) rotate(15deg); }
}

/* 多层次云雾 */
.fog:nth-child(1) {
  top: 20%;
  left: -50%;
  opacity: 0.7;
  animation-duration: 35s;
}
.fog:nth-child(2) {
  top: 60%;
  filter: blur(60px);
  animation-duration: 45s;
}
