原代码为:

<div class="container">
<h2>Accordion Example</h2>
<p><strong>Note:</strong> The <strong>data-parent</strong> attribute makes sure that all collapsible elements under the specified parent will be closed when one of the collapsible item is shown.</p>
<div class="panel-group" id="accordion">

<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion" href="#collapse1">Collapsible Group 1</a>

<div id="collapse1" class="panel-collapse collapse in">
<div class="panel-body">Lorem ipsum dolor sit amet, consectetur adipisicing elit,

我希望在容器之前添加元素符号点,使其看起来像这样。

ScreenShot

我尝试添加 <ul <li>之前<div class="panel panel-default"></li> </ul><div class="panel-body">Lorem ipsum dolor sit amet, consectetur adipisicing elit....</div> 之后它可以获取每个框的元素符号点,但如果单击第一个框以外的另一个框,则不允许关闭框。

希望有人能提供帮助,我对 HTML 的经验为 0,并且这样做很有趣,所以如果您不想提供帮助,请不要发表评论。谢谢

最佳答案

你可以使用伪元素 :after:before 来获取子弹。

.panel.panel-default:before {
content: '';
position: absolute;
left: -10px;
width: 4px;
height: 4px;
border-radius: 50%;
background: black;
top: 15px;
}

.panel.panel-default {
position: relative;
}
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

<div class="container">
<h2>Accordion Example</h2>
<p><strong>Note:</strong> The <strong>data-parent</strong> attribute makes sure that all collapsible elements under the specified parent will be closed when one of the collapsible item is shown.</p>
<div class="panel-group" id="accordion">

</div>
</div>
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
