徽章
在 Bootstrap 中，徽章（Badges）是一种用于突出显示新的、更新的或有未读项的元素。它们通常用于通知用户有新的消息、更新或其他需要关注的内容。
使用徽章的基本方式是将 .badge 类添加到一个 <span> 元素上，同时根据需要添加一个背景颜色类，例如 .bg-primary、.bg-secondary、.bg-success 等。注意：徽章会在父元素大小变化时自动调整其大小，这也是一个很方便的特性。

进度条
基础进度条
进度条可以显示用户任务的完成过程。
创建一个基本的进度条的步骤如下：
- 添加一个带有 .progress 类的 <div>。
- 接着，在上面的 <div> 内，添加一个带有 class="progress-bar" 的空的 <div>。
- 添加一个带有百分比表示的宽度的 style 属性，例如 style="width:50%" 表示进度条在 50% 的位置。

</html>运行结果：
进度条高度
进度条的高度通常默认为1rem（或16px），可以通过CSS的height属性来更改。如果想要改变进度条的高度，需要针对进度条（.progress-bar）和进度条的容器（.progress）应用相同的高度值。
