官网:https://getbootstrap.com/
GitHub 主页:https://github.com/twbs/bootstrap
release 页面:https://github.com/twbs/bootstrap/releases

下载

从官方发布页下载:

wget https://github.com/twbs/bootstrap/releases/download/v4.4.1/bootstrap-4.4.1-dist.zip
unzip bootstrap-4.4.1-dist.zip

引用

如果只想使用 bootstrap 的 css 特性,在 <head> 标签内 link:

    <link rel="stylesheet" href="path/to/bootstrap.min.css">

如果想要全套的交互响应功能,需要 jQuery,popper.js 框架和引用 bootstrap.js 文件,注意引用顺序不能乱,jQuery must come first, then Popper.js, and then our JavaScript plugins,将一下 script 放到结束符号 </body> 标签前:

<script src="path/to/jquery.min.js"></script>
<script src="path/to/popper.min.js"></script>
<script src="path/to/bootstrap.min.js"></script>

breadcrumb

官网简介:https://getbootstrap.com/docs/4.4/components/breadcrumb/

breadcrumb 可以指明当前页面层级关系,使用 css 定义的符号进行分割。

<nav aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item active" aria-current="page">Home</li>
  </ol>
</nav>

<nav aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item"><a href="#">Home</a></li>
    <li class="breadcrumb-item active" aria-current="page">Library</li>
  </ol>
</nav>

<nav aria-label="breadcrumb">
  <ol class="breadcrumb">
    <li class="breadcrumb-item"><a href="#">Home</a></li>
    <li class="breadcrumb-item"><a href="#">Library</a></li>
    <li class="breadcrumb-item active" aria-current="page">Data</li>
  </ol>
</nav>

为了为障碍浏览提供方便,针对面包屑这样具备导航功能的模块,建议添加一个有意义的标签:aria-label="breadcrumb" 來描述 <nav> 元素,以及使用 aria-current="page" 到这组导航的最后一个项目,以标明当前页面名称(路径)。

修改默认分割符:

<style>
    .breadcrumb-item + .breadcrumb-item::before {
        content: ">";
    }
</style>
