CSS：如何将箭头附加到div并使其与边框重叠 [英] CSS: How to attach an arrow to a div and make it overlap the border

问题描述

我想让一个popover有错误，但我有困难，使箭头出现在我附加的div的边框之上。

I am trying to make a popover with an error, but I am having trouble making the arrow appear above the border of the div I am attaching it to. I would appreciate any help.

这是我到目前为止...

This is what I have so far...

这是CSS代码我使用，但无法让它工作：

This is the CSS code I am using, but cant get it to work:

1.DIV为整个popover：

1.DIV for the entire popover:

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

2.CSS每个：

.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;
}
