   面包屑导航（独立样式，可复用到任意页面）
   ------------------------------------------------------------
   用法：在 <header> 之后直接插入以下结构即可，样式自带，
   不依赖其他 CSS 文件：
     <div class="breadcrumb-bar">
       <div class="wh1200 breadcrumb">
         <a href="/">首页</a>
         <span class="sep">/</span>
         <a href="/product.html">产品中心</a>
         <span class="sep">/</span>
         <span class="current">当前栏目</span>
       </div>
     </div>
