我有这样的图像:
<img id="item_img" src="https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcRH7oGdODLKgm4gaTYHdWDPYLUASSrLYxW4-YDuaZz-iU8jx5_3jg" alt="" height="333px" width="500px" />
使用css:
#item_img:hover {
opacity: 0.4;
}
使用此代码,我在悬停时应用了一点不透明度。另外,我想在图像中间显示悬停处于活动状态时的共享图标:
我该怎么做?

您可以使用css psuedo class after
执行此操作。
通过使用after来实现这一目标,您不必在HTML代码中实际添加悬停图像。
.img-div{position:relative; display: inline-block;}
.img-div:hover:after{
content:'';
position:absolute;
left: 0px;
top: 0px;
bottom: 0px;
width: 100%;
background: url('http://i.stack.imgur.com/P1ELC.png') center no-repeat;
background-size: 50px;
}
.img-div:hover img{opacity: 0.4;}
&#13;
<div class="img-div">
<img src="http://placehold.it/150x150"/>
</div>

或者让它更简单! http://jsfiddle.net/oneeezy/5bDKz/2/
为此你会改变我的背景:黑色;到背景:url(&#34; your-image.jpg&#34;)no-repeat 0 0;
div { position: relative; overflow: hidden; float: left; border-radius: 13em; }
div img { width: 100px; height: 100px; float: left; position: relative; display: block; }
/* Hover Effect */
div:hover:after { content: ""; position: absolute; top: 50%; left: 50%; width: 25px; height: 25px; margin: -15px 0 0 -15px; background: black; border-radius: 3em; border: 2px solid white; }
