【问题描述】：

我正在尝试在可折叠面板中使用 Bootstrap Scrollspy。一切似乎都在工作，除了当我点击它们时药片没有更新/改变颜色。我想我必须更改 CSS，但我不确定我需要更改什么。

标签： html css twitter-bootstrap scrollspy

【解决方案1】：

您忘记在第一个 body 标记上添加一些自定义引导属性。这将使药丸按钮突出显示，尽管您很快就会发现您会遇到另一个小问题。高亮状态将跳过最后两个按钮，从 4 到 7，因为滚动条会太快到达浏览器底部。我猜这会有点棘手。这也取决于每个部分文本的长度

HTML：

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

【讨论】：

谢谢。我明白你的意思了。它现在跳到最后一个按钮上。有什么办法可以解决这个问题吗？

【解决方案2】：

我使用了推荐的自定义引导属性。

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;
  }
