CSS：鼠标移出时的过渡不透明度？

css

.item:hover {
zoom: 1;
filter: alpha(opacity=50);
opacity: 0.5;
-webkit-transition: opacity .15s ease-in-out;
-moz-transition: opacity .15s ease-in-out;
-ms-transition: opacity .15s ease-in-out;
-o-transition: opacity .15s ease-in-out;
transition: opacity .15s ease-in-out;
}

为什么当我将鼠标悬停在鼠标上时，为什么只在不透明度上设置动画呢？

您仅将转换应用于:hover伪类，而不应用于元素本身。

.item {   
  height:200px;
  width:200px;
  background:red; 
  -webkit-transition: opacity 1s ease-in-out;
  -moz-transition: opacity 1s ease-in-out;
  -ms-transition: opacity 1s ease-in-out;
  -o-transition: opacity 1s ease-in-out;
  transition: opacity 1s ease-in-out;
}

.item:hover {
  zoom: 1;
  filter: alpha(opacity=50);
  opacity: 0.5;
}

如果您只希望过渡不影响mouse-over事件，mouse-out则可以为:hoverstate 关闭过渡：

.item:hover {
  -webkit-transition: none;
  -moz-transition: none;
  -ms-transition: none;
  -o-transition: none;
  transition: none;
  zoom: 1;
  filter: alpha(opacity=50);
  opacity: 0.5;
}
