<div class="image-container">
  <img src="image.jpg" alt="Image">
  <div class="overlay"></div>
</div>

.image-container {
  position: relative;
  display: inline-block;
}

.image-container img {
  display: block;
  width: 100%;
  height: auto;
}

.image-container .overlay {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background-color: rgba(0, 0, 0, 0.5);
  opacity: 0;
  transition: opacity 0.3s ease;
}

.image-container:hover .overlay {
  opacity: 1;
}

.image-container .overlay {
  /* ... */
  display: flex;
  align-items: center;
  justify-content: center;
  color: #fff;
  text-align: center;
}

.image-container .overlay::before {
  content: "点击查看详情";
  font-size: 18px;
}

.image-container .overlay:hover {
  cursor: pointer;
  background-color: rgba(0, 0, 0, 0.7);
}
