Question

我想在我悬停图像时出现背景颜色，因此我为图像添加了1的不透明度和背景颜色，当图像悬停时不透明度为0.5，因此可以显示背景颜色。但背景颜色不会出现。

.article-preview-image img {
  background-color: #58b253 !important;
}
.article-preview-image img {
  opacity: 1 !important;
  -webkit-transition: .3s ease-in-out !important;
  transition: .3s ease-in-out !important;
}
.article-preview-image:hover img {
  opacity: 0.5 !important;
}

Answer 1

不要在图像上设置背景颜色，而是在图像容器上设置它。

当图像悬停时，应用不透明度，使图像透明，并且可以看到容器上的背景颜色。

.article-preview-image {
    display: inline-block; /* element takes content width */
    background-color: red; /* for demo purposes */
}
.article-preview-image img {
   transition: .3s ease-in-out;
}
.article-preview-image:hover img {
   opacity: 0.5;
}
