我正在尝试制作一个有错误的弹出框,但是我无法让箭头出现在我要附加到的 div 的边框上方。我将不胜感激任何帮助。

这是我目前所拥有的......

这就是我所拥有的...

这是我正在使用的 CSS 代码,但无法正常工作:

1.DIV为整个popover:

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

2.CSS为每个:

.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;
}

最简单的方法:

HTML:

<div class="meow">
</div>

CSS:

.meow { 
  height: 100px;
  width: 300px;
  margin: 30px;
  background: linear-gradient(#333, #222);
  -o-border-radius: 4px;
  -ms-border-radius: 4px;
  -moz-border-radius: 4px;
  -webkit-border-radius: 4px;
  border-radius: 4px;
}

.meow:after {
  content: " ";
  border-top: 11px solid #222;
  border-left: 8px solid transparent;
  border-right: 8px solid transparent;
  position: relative;
  top: 111px;
  right: -140px;
}

只需做一些编辑。

尝试这个:

HTML

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

CSS

.info-popover {
    position: relative;
    /* any other CSS */
}

.arrow {
    background: url("/images/dock/popover-arrow.png") no-repeat 0 0;
    height: 15px;
    width: 20px; /* width of arrow image? */
    display: block;
    position: absolute;
    bottom: -15px;
    left: 0; margin: 0 auto; right: 0; /* to center the arrow */
}
