我正在尝试连接 Bootstrap 5。我在互联网上发现了两种方法：

方法一：

<!doctype html>
<html lang="ru">
<head>
    <title>Заголовок</title>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <!-- Bootstrap: подключение с помощью CDN -->
    <link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css"
          rel="stylesheet"
          integrity="sha384-1BmE4kWBq78iYhFldvKuhfTAU6auU8tT94WrHftjDbrCEXSU1oBoqyl2QvZ6jIW3"
          crossorigin="anonymous">
    <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js"
            integrity="sha384-ka7Sk0Gln4gmtz2MlQnikT1wXgYsOg+OMhuP+IlRH9sENBO0LRn5q+8nbTov4+1p"
            crossorigin="anonymous"></script>

</head>
<body>

<div class="container">
    <button class="btn btn-primary">Button 1</button>
</div>

</body>
</html>

方法2：

<!doctype html>
<html lang="ru">
<head>
    <title>Заголовок</title>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <!-- Bootstrap CSS -->
    <link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css"
          rel="stylesheet"
          integrity="sha384-1BmE4kWBq78iYhFldvKuhfTAU6auU8tT94WrHftjDbrCEXSU1oBoqyl2QvZ6jIW3"
          crossorigin="anonymous">


</head>
<body>

<div class="container">
    <button class="btn btn-primary">Button 2</button>
</div>

<!-- Bootstrap JS -->
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js"
        integrity="sha384-ka7Sk0Gln4gmtz2MlQnikT1wXgYsOg+OMhuP+IlRH9sENBO0LRn5q+8nbTov4+1p"
        crossorigin="anonymous"></script>

</body>
</html>

结果，从按钮的外观来看，在这两种情况下 Bootstrap 都已连接：

在此输入图像描述

我有一个问题：这些方法有什么区别？在实践中我应该使用哪一种？

当然，从视觉上看，第一个选项看起来更好：两个链接都紧凑地写在 head 标签中的一个位置。而在第二个版本中，JS的链接被拖到了body标签中，拖到了最底部（看起来不太漂亮，但可能有一些意义）。

一般来说，为什么在这两种情况下都连接一些 JS？ Bootstrap是一个纯粹的布局工具。

mb-md-0 me-md-auto这些Bootstrap 5.2属性是如何解码的？

      <a href="/" class="d-flex align-items-center mb-3 mb-md-0 me-md-auto text-dark text-decoration-none">
        <span class="fs-4">Simple header</span>

有这个侧边栏： 在此处输入图像描述

如您所见，它没有拉伸到页面的整个高度。

但是如果你在它旁边插入任何文本，它就会开始像这样拉伸： 在此处输入图像描述

我该如何解决这个问题，以便面板始终是全高的？

这是我的代码：

我使用select2，如果从下拉列表中选择不正确，则需要用俄语写一条消息：

这是代码：

<html>
<head>
    <title>Демка выпадающего списка Select2</title>  
    <script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
    <link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/css/select2.min.css" rel="stylesheet" />
    <script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/js/select2.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/js/i18n/ru.js"></script>
    <!-- <script src="https://cdn.jsdelivr.net/npm/select2@4.1.0-rc.0/dist/js/i18n/ru.js"></script> -->
</head>
<body>
<div style="width:520px;margin:0px auto;margin-top:30px;height:500px;">
  <h2>Демка выпадающего списка Select2</h2>
  <select class="myselect" style="width:500px;">
      <option>Вася</option>
      <option>Петя</option>
      <option>Федя</option>
      <option>Николай</option>
      <option>Сережа</option>
      <option>Наташа</option>
      <option>Танька</option>
      <option>Машка</option>
  </select>
</div>
<script type="text/javascript">
      $.fn.select2.defaults.set('language', 'de');
      $.fn.select2.defaults.set('allowClear', true);
      $.fn.select2.defaults.set('width', '100%');
      $(".myselect").select2(); 
</script>

该行$.fn.select2.defaults.set('language', 'your-lang');公开了语言，但不是全部。德语，波兰语，英语，西班牙语......例如俄语，法语，不想。这条线有一个细微差别 - 给了我我需要的东西。但我认为这是一个拐杖。
