标签: css css3 popover

我正在尝试使用错误制作一个弹出框,但是我无法使箭头出现在我附加到div的边框上方。我将不胜感激任何帮助。

这就是我到目前为止......

This is what I have...

这是我正在使用的CSS代码,但无法让它工作:

1.DIV为整个popover:

<div class="info-popover">
    <div class="inner"></div>
    <div class="arrow"></div>
</div>

2.CSS for each:

.info-popover {
    height: 250px;
    margin-top: -255px;
    position: absolute;
    width: 400px;
}

.info-popover .inner {
    background-color: #FFFFFF;
    border: 1px solid #003366;
    border-radius: 10px 10px 10px 10px;
    height: 240px;
    margin-top: 0;
    width: 100%;
}

.info-popover .arrow {
    background: url("/images/dock/popover-arrow.png") no-repeat scroll center -5px transparent;
    height: 15px;
    position: relative;
    width: 100%;
    z-index: 999;
}

最简单的方法:
