我不明白为什么我的进度条不起作用。我想我的引导程序的 css 选项有问题。我试图更改选项以找出问题所在，但没有成功。

看法

 <div class="progress progress-success progress-striped">
 <div class="bar" style="width:20%"></div>
 </div>

css

您的代码看起来不错 - 但是，要使进度条“工作”，您还必须为width.

有很多方法可以做到这一点，但您必须选择最适合您的页面或页面体验的方法。例如，您可能有 5 页，就像在调查中一样。进度条将是每个页面上的持久元素。在创建每个页面时，您会想要更改宽度的内联样式，可能是这样的：

<div class="bar" style="width:20%"></div>
<div class="bar" style="width:40%"></div>
<div class="bar" style="width:60%"></div>
<div class="bar" style="width:80%"></div>
<div class="bar" style="width:100%"></div>

当您这样做时，进度条的可视化将被更新。在单页和多页中都有很多方法可以做到这一点，但以上只是一个示例。

这是一个供您使用的工作示例：
