Jquery 引导程序中未正确加载徽章

My index.html未在任何浏览器上正确显示徽章。它不是在彩色圆圈中显示数字。它只是显示它好像没有正确加载CSS

我尝试了bootstrap和jquery中的本地和CDN路径，但问题没有得到解决

缺少颜色类，例如

<span class="badge badge-primary">5</span>

您正在使用引导程序4

只需将span类更改为badge badge secondary

<a href="#">Messages <span class="badge badge-secondary">5</span> </a>

请参阅此引导文档：

徽章颜色更改：

<span class="badge badge-primary">Primary</span>
<span class="badge badge-secondary">Secondary</span>
<span class="badge badge-success">Success</span>
<span class="badge badge-danger">Danger</span>
<span class="badge badge-warning">Warning</span>
<span class="badge badge-info">Info</span>
<span class="badge badge-light">Light</span>
<span class="badge badge-dark">Dark</span>

要使徽章圆形，请添加类徽章药丸

<span class="badge badge-pill badge-primary">Primary</span>
<span class="badge badge-pill badge-secondary">Secondary</span>
<span class="badge badge-pill badge-success">Success</span>
<span class="badge badge-pill badge-danger">Danger</span>
<span class="badge badge-pill badge-warning">Warning</span>
<span class="badge badge-pill badge-info">Info</span>
<span class="badge badge-pill badge-light">Light</span>
<span class="badge badge-pill badge-dark">Dark</span>

试试这个解决方案
