1、滚动条

  1. <style>
  2.     .scrollBody {
  3.         position: relative;
  4.         height: 200px;
  5.         overflow-y: scroll;

  9. </style>
  10. <div class="container">

  12.         <div class="col">
  13.             <!-- 在导航当中的滚动 -->
  14.             <nav class="navbar navbar-light bg-light" id="scroll1"> <!-- 这个id是要与下面的内容相对应 -->

  30.             <!-- 
  31.                 滚动元素
  32.                     1、它不是body元素，所以身上要添加两条样式，heigh与overflow-y
  33.                     2、data-spy="scroll"。让这个元素具有滚动监听的js功能
  34.                     3、data-target="#scroll1"    监听的那个导航的id
  35.                     4、data-offset="0"   计算滚动位置时的偏移量。值为0，就表示从0的位置就开始计算
  36.                     5、上面结构中每一个导航都有一个#id。那在这块的内容区域就需要有一个标题具有一个id，与上面的值一一对应的
