如何使图像动画对叠加文本生效？

Question

我为一个图像制作了一个动画，在悬停时使用叠加文字将其从黑白变为彩色，但当悬停在叠加文本图像上时，图像会变回黑白。我怎样才能保持它的颜色？

这是我的代码：

#img {
  filter: gray; /* IE6-9 */
  -webkit-filter: grayscale(1); /* Google Chrome, Safari 6+ & Opera 15+ */
  -webkit-box-shadow: 0px 2px 6px 2px rgba(0,0,0,0.75);
  -moz-box-shadow: 0px 2px 6px 2px rgba(0,0,0,0.75);
  box-shadow: 0px 2px 6px 2px rgba(0,0,0,0.75);
  margin-bottom:20px;
}
#img:hover {
  filter: none; /* IE6-9 */
  -webkit-filter: grayscale(0); /* Google Chrome, Safari 6+ & Opera 15+ */
}
.middle {
  transition: .5s ease;
  opacity: 0;
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  -ms-transform: translate(-50%, -50%)
}
.container1:hover .image {
  opacity: 0.3;
}

.container1:hover .middle {
  opacity: 1;
}

.text {
  background-color: rgb(45, 45, 65);
  color: rgb(255, 250, 235);
  text-align: center;
  font-size: 14px;
  padding: 16px 32px;
}

您只需将元素的:hover selector从#img:hover更改为.container1:hover #img，因此每当mouseenter容器将样式属性添加到#img时。

.container1:hover #img {
  filter: none;
  /* IE6-9 */
  -webkit-filter: grayscale(0);
  /* Google Chrome, Safari 6+ & Opera 15+ */
}

#img {
  filter: gray;
  /* IE6-9 */
  -webkit-filter: grayscale(1);
  /* Google Chrome, Safari 6+ & Opera 15+ */
  -webkit-box-shadow: 0px 2px 6px 2px rgba(0, 0, 0, 0.75);
  -moz-box-shadow: 0px 2px 6px 2px rgba(0, 0, 0, 0.75);
  box-shadow: 0px 2px 6px 2px rgba(0, 0, 0, 0.75);
  margin-bottom: 20px;
}

.middle {
  transition: .5s ease;
  opacity: 0;
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  -ms-transform: translate(-50%, -50%)
}

.container1:hover .image {
  opacity: 0.3;
}

.container1:hover .middle {
  opacity: 1;
}

.container1:hover #img {
  filter: none;
  /* IE6-9 */
  -webkit-filter: grayscale(0);
  /* Google Chrome, Safari 6+ & Opera 15+ */
}

.text {
  background-color: rgb(45, 45, 65);
  color: rgb(255, 250, 235);
  text-align: center;
  font-size: 14px;
  padding: 16px 32px;
