如何使用 Bootstrap Scrollspy 更新药丸的背景颜色？

Question

我正在尝试在可折叠面板中使用 Bootstrap Scrollspy。一切似乎都正常，除了当我点击它们时药丸没有 update/change 颜色。我想我必须更改 CSS 但我不确定我需要更改什么。

HTML

<body>

CSS

  body {
  position: relative;
  }

ul.nav-pills {
      top: 50px;
      position: fixed;
  }

  div.col-sm-9 div {
      height: 250px;
      font-size: 28px;
  }

Answer 1

您忘记在第一个 body 标签上添加一些自定义 bootstrap 属性。这将使药丸按钮突出显示，尽管您很快就会发现您会运行陷入另一个小问题。突出显示的状态将跳过最后两个按钮，从 4 到 7，因为滚动条到达浏览器底部的速度太快。我想这会有点棘手。也将取决于每个部分文本的长度

HTML:

<body data-spy="scroll" data-target="#myScrollspy">

Answer 2

我使用了推荐的自定义 bootstrap 属性。

HTML

<body data-spy="scroll" data-target="#myScrollspy">

然后我更改了 CSS 中每个部分的高度以解决跳跃问题。

CSS

  #Subtitle1,
  #Subtitle2,
  #Subtitle3,
  #Subtitle4,
  #Subtitle5,
  #Subtitle6,
  #Subtitle7 {
      height: 500px;
  }
