Question

您好我正在尝试创建悬停效果，因此当有人将鼠标悬停在具有LI元素的图像上时，此图像保持完全不透明，但oitehr LI元素稍微淡出。我知道这可以做到，但目前我的代码正在逐渐淡出。

请在我的代码下面找一个小提琴。

非常感谢任何帮助。

.imageWrapper {
  position: relative;
  z-index: 5;
}

.imageWrapper:after {
  content: " ";
  position: absolute;
  width: 100%;
  height: 100%;
  top: 0;
  left: 0;
  display: block;
  z-index: 10;
  transition: background 0.3s linear;
}

.cpClientIcon {
  /*
  .cpImageWithTitle {
    .title {
      @include opacity(0);
      transition:opacity 0.3s linear;
    }
  }
*/
}

.cpClientIcon:hover .imageWrapper:after, .cpClientIcon:focus .imageWrapper:after, .cpClientIcon:active .imageWrapper:after {
  background: red;
}

.cpClientIcon:hover .imageWrapper:hover, .cpClientIcon:hover .imageWrapper:focus, .cpClientIcon:hover .imageWrapper:active, .cpClientIcon:focus .imageWrapper:hover, .cpClientIcon:focus .imageWrapper:focus, .cpClientIcon:focus .imageWrapper:active, .cpClientIcon:active .imageWrapper:hover, .cpClientIcon:active .imageWrapper:focus, .cpClientIcon:active .imageWrapper:active {
  /*
        .title {
          @include opacity(1);
        }
*/
}

.cpClientIcon:hover .imageWrapper:hover .imageWrapper:after, .cpClientIcon:hover .imageWrapper:focus .imageWrapper:after, .cpClientIcon:hover .imageWrapper:active .imageWrapper:after, .cpClientIcon:focus .imageWrapper:hover .imageWrapper:after, .cpClientIcon:focus .imageWrapper:focus .imageWrapper:after, .cpClientIcon:focus .imageWrapper:active .imageWrapper:after, .cpClientIcon:active .imageWrapper:hover .imageWrapper:after, .cpClientIcon:active .imageWrapper:focus .imageWrapper:after, .cpClientIcon:active .imageWrapper:active .imageWrapper:after {
  background: transparent;
}

/* Clients Page */
.cpClientIcon {
  background: #fff;
}

.cpClientIcon.ClientIcon {
  width: 100%;
}

.cpClientIcon.ClientIcon ul li {
  width: 25%;
  display: inline-block;
  padding: 0;
  margin: 0;
  float: left;
}

.cpClientIcon.ClientIcon ul li.imageWrapper {
  position: relative;
}

.cpClientIcon.ClientIcon ul li.imageWrapper span {
  position: absolute;
  bottom: 0;
  opacity: 0;
  transform: translate(-50%, 0);
  left: 50%;
  background: rgba(0, 0, 0, 0.8);
  color: #fff;
  width: 100%;
  text-align: center;
  padding: 1em 0;
  transition: all 0.5s ease;
}

.cpClientIcon.ClientIcon ul li.imageWrapper:hover span {
  opacity: 1;
}

.cpClientIcon.ClientIcon ul li img {
  width: 100%;
  height: auto;
}

Answer 1

设置UL的悬停规则，将所有子LI元素设置为所需的淡化不透明度，然后为LI设置悬停规则，将不透明度设置回完全不透明：

ul:hover li {
  opacity: 0.5;
}

ul:hover li:hover {
  opacity: 1;
}

您也可以使用mix-blend-mode：

＆＃13;

 li a {
   background: rgba(255, 255, 255, 0.5);
   display: inline-block;
   width:100%;
 }
 
 li * {
   mix-blend-mode: soft-light;
 }
 
 li:hover * {
   mix-blend-mode: unset;
 }
li {display:inline-block;width:20%;}
img {max-width:100%;}

可以对li内的任何元素执行，也可以仅对img：https://jsfiddle.net/dfLk3gy5/1/

执行
