使用CSS在div中保留浮动图像

<div class="container">
  <img src="your-image-source.jpg" alt="Your Image" class="floating-image">
</div>

.container {
  position: relative;
  width: 100%;
  height: 200px;
  border: 1px solid #000;
  overflow: auto;
}

.floating-image {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  max-width: 100%;
  max-height: 100%;
}
