Question

我创建了一个用户hovercard，但我有z-index问题。

如果您可以查看此演示，那么您可以看到有树形图= DEMO

将鼠标悬停在任何图像上，然后hovercar将打开，但Hovercard远远低于下图。我怎么能解决它，任何人都可以帮助我吗？

<div class="the-container">
    <div class="summary-mask"></div>
    <div class="summary" data-id="50"> <a href="http://kraigo.tumblr.com/" class="profile-ava"></a>
        <div class="user-container"></div>
    </div>
</div>

CSS

.summary-mask {
    margin: 50px auto 0;
    width: 50px;
    height: 50px;
    position: relative;
    z-index: 1;
}
.loaded .summary-mask {
    z-index: -1;
}
.profile-ava {
    width: 50px;
    height: 50px;
    background-image: url(http://gravatar.com/avatar/3913c4e14034c0a7f28db2c632290c21?s=80);
    border-radius: 3px;
    background-size: 50px 50px;
    display: block;
}
.summary a:hover:before {
    content:'';
    position: absolute;
    display: block;
    bottom: -10px;
    left: 0;
    height: 10px;
    width: 100%;
    z-index: 2;
}
.p-tooltip {
    position: absolute;
    margin-top: 10px;
    top: 100%;
    left: 50%;
    margin-left: -140px;
    width: 280px;
    max-height: 120px;
    border-radius: 5px;
    overflow: hidden;
    background-color: #F0F0F0;
    visibility: hidden;
    opacity: 0;
    transition: all 0.5s ease;
}

这应该有效：

删除你在那里的所有花哨的z-index样式，只需在工具提示中添加一个正z-index z-index:999;：

.summary {
    margin: -50px auto 0;
    width: 50px;
    height: 50px;
    position: relative;
}
.summary-mask {
    margin: 50px auto 0;
    width: 50px;
    height: 50px;
    position: relative;
}
.p-tooltip {
    position: absolute;
    margin-top: 10px;
    top: 100%;
    left: 50%;
    margin-left: -140px;
    width: 280px;
    max-height: 120px;
    border-radius: 5px;
    overflow: hidden;
    background-color: #F0F0F0;
    visibility: hidden;
    opacity: 0;
    transition: all 0.5s ease;
    z-index:999;
}

CSS z-index不起作用
