如何使引导程序崩溃平滑

问题描述

我这里有这个代码。正如您所看到的，当内容折叠时，在内容折叠之前会有一个轻弹。我需要它顺利折叠。

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script>


<div class="container">
  <h2>Simple Collapsible</h2>
  <p>Click on the button to toggle between showing and hiding content.</p>
  <button type="button" class="btn btn-info" data-toggle="collapse" data-target="#demo">Simple collapsible</button>
  <div id="demo" class="collapse in">
    Lorem ipsum dolor sit amet,consectetur adipisicing elit,sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam,quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
  </div><br>
  <button type="button" class="btn btn-info" data-toggle="collapse" data-target="#demo2">Simple collapsible</button>
  <div id="demo2" class="collapse in">
    Lorem ipsum dolor sit amet,quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
  </div>
</div>

解决方法

将您的内容包装到 2 个容器 div 中并移除 br（或将 br 放在容器 div 之外）

<div class="container">
    <button type="button" class="btn btn-info" data-toggle="collapse" data-target="#demo2">
    Simple collapsible
    </button>
    <div id="demo2" class="collapse in">Lorem ...</div>
</div>
<div class="container">
    <button type="button" class="btn btn-info" data-toggle="collapse" data-target="#demo2">
    Simple collapsible
    </button>
    <div id="demo2" class="collapse in">Lorem...</div>
</div>

示例：

<!DOCTYPE html>
<html>
<head>
  <meta name="viewport" content="width=device-width,initial-scale=1">
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script>
</head>
<body>

<div class="container">
  <h2>Simple Collapsible</h2>
  <p>Click on the button to toggle between showing and hiding content.</p>
  
  <div class="container">
    <button type="button" class="btn btn-info" data-toggle="collapse" data-target="#demo">
    Simple collapsible
    </button>
    <div id="demo" class="collapse in">
      Lorem ipsum dolor sit amet,consectetur adipisicing elit,sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam,quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
    </div>
  </div>
  <div class="container">
    <button type="button" class="btn btn-info" data-toggle="collapse" data-target="#demo2">
    Simple collapsible
    </button>
    <div id="demo2" class="collapse in">
      Lorem ipsum dolor sit amet,quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
    </div>
  </div>
</div>
    
</body>
</html>
