嗨，我需要在img中显示img的Title标签。

就像这个例子http://jsfiddle.net/51csqs0b/

.image {
    position:relative;
    width:200px;
    height:200px;
}
.image img {
    width:100%;
    vertical-align:top;
}
.image:after, .image:before {
    position:absolute;
    opacity:0;
    transition: all 0.5s;
    -webkit-transition: all 0.5s;
}
.image:after {
    content:''A';
    width:100%; height:100%;
    top:0; left:0;
    background:rgba(0,0,0,0.6);
}
.image:before {
    content: attr(data-content);
    width:100%;
    color:#fff;
    z-index:1;
    bottom:0;
    padding:4px 10px;
    text-align:center;
    background:red;
    box-sizing:border-box;
    -moz-box-sizing:border-box;
}
.image:hover:after, .image:hover:before {
    opacity:1;
}

<div data-content="Here is a caption" class="image">
    <img src="https://i.stack.imgur.com/Sjsbh.jpg" alt="" />
</div>
<hr>
    
<div data-content="Different caption here..." class="image">
    <img src="https://i.stack.imgur.com/Sjsbh.jpg" alt="" />
</div>

但是我不想在img之前使用div

<a href="#"><img class="" title="TITLE NEED SHOW ON HOVER" src=""/></a>

有可能出现吗?由于

这是我所能做的:

add .image class to a

<a class="image" href="#"><img src="https://i.stack.imgur.com/Sjsbh.jpg" class="" title="TITLE NEED SHOW ON HOVER" src=""/></a>

用title代替data-content:

.image:before {
    content: attr(title);
    width:100%;
    color:#fff;
    z-index:1;
    bottom:0;
    padding:4px 10px;
    text-align:center;
    background:red;
    box-sizing:border-box;
    -moz-box-sizing:border-box;
}

最后，添加以下jQuery代码:

$("a.image").each(function(){$(this).attr('title',$(this).find("img").attr('title'))});

在这里自己运行:

这里有一个更简单的方法。你只需要在悬停的伪元素之后使用:。纯CSS解决方案

<a href="" class="img"></a>
.img{
  display: block;
  width:200px;
  height:200px;
  background: url('https://i.stack.imgur.com/Sjsbh.jpg');
  background-size: 200px 200px;
  position: relative;
}
.img:hover::after {
  content:'This is a description';
  position: absolute;
  width:100%; 
  height:20%;
  bottom:0; left:0;
  background: rgba(255, 255, 255, 0.8);
 }

你不会很具体。我希望它会有所帮助。你也可以做一个工具提示
