悬停放大和缩小背景无法正常工作



我正在尝试为图像添加悬停效果以进行放大和缩小。但是立即工作缩小效果,而无需将鼠标指针移到图像上。

.container {
  overflow: hidden;
  position: relative;
  width: 50%;
}
.image {
  display: block;
  width: 100%;
  height: auto;
  background-size: cover;
  background-position: center;
  transition: all 0.5s ease;
}
.overlay {
  position: absolute;
  bottom: 0;
  left: 0;
  right: 0;
  background-color: black;
  overflow: hidden;
  width: 100%;
  height: 0;
  transition: .5s ease;
  opacity: 0.5;
}
.container:hover .overlay {
  height: 100%;
}
.text {
  color: white;
  font-size: 20px;
  position: absolute;
  top: 50%;
  left: 50%;
  -webkit-transform: translate(-50%, -50%);
  -ms-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
  text-align: center;
}
.image:hover {
  transform: scale(1.5);
  transition: .5s ease;
}

实际上,我想为图像添加悬停效果,当鼠标指针出现在图像上时,它会平滑放大,当鼠标指针移到图像上时,它会缩小。

我了解,您希望在鼠标悬停在卡片上时进行放大,并在鼠标从卡片上移出时立即进行缩小。如果是这种情况,下面的代码片段应该是此问题的修复程序:

.container {
  overflow: hidden;
  position: relative;
  width: 50%;
}
.image {
  display: block;
  width: 100%;
  height: auto;
  background-size: cover;
  background-position: center;
  transition: all 0.5s ease;
}
.overlay {
  position: absolute;
  bottom: 0;
  left: 0;
  right: 0;
  background-color: black;
  overflow: hidden;
  width: 100%;
  height: 0;
  transition: .5s ease;
  opacity: 0.5;
}
.container:hover .overlay {
  height: 100%;
}
.text {
  color: white;
  font-size: 20px;
  position: absolute;
  top: 50%;
  left: 50%;
  -webkit-transform: translate(-50%, -50%);
  -ms-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
  text-align: center;
}
.container:hover .image {
  transform: scale(1.5);
  transition: .5s ease;
}

问题在于,您在.image:hover上做出了反应,并且由于存在叠加层,一旦叠加层遮盖了图像,css 引擎就会从图像中删除:hover。将:hover的目标更改为.container可确保即使叠加遮挡了图像,它也会存在。

当叠加层到达指针时,它会缩小。当叠加层到达指针时,实际上是叠加层获得悬停效果,而不再是图像。

您可以通过向.container:hover .overlay css 添加.pointer-events: none来避免这种情况,如下所示:

.container:hover .overlay {
  height: 100%;
  pointer-events: none;
}
