Bootstrap 单击时面包屑进入中心 div

Question

我建立了一个站点地图页面，并在顶部使用面包屑将用户带到他们寻找的直接位置感觉它有点长。但是，当他们单击面包屑时，进入正确的 div，但进入下方。

这是我的代码

<div class="container" style="border: 1px solid black;">
    <div class="row" style="border: 1px solid black; background-color: #3a5d85; ">
            <h3 style="text-align: center; font-size: 40px;"><b>Site Map</b></h3>

        <ul class="breadcrumb" style="font-size: 18px;">
            <li class="actve"><a href="#Company">Company</a>

我可以使用完全相同的代码让它在 JSfiddle 中工作 jsfiddle link

这是我正在处理的网站，Working website

正如您在我的工作网页上看到的那样，它将超过 header 几行？

Answer 1

因为你有一个固定的header，你需要padding到header高度的元素和一个相同高度的负margin到偏移固定 header 高度的元素。创建一个名为 .fake-margin 的 class 到具有用于 href="#{idlink}" 的 id 链接的元素，并给出以下 CSS:

.fake-margin {
  margin-top: -72px; /* Header height + margin */
  padding-top: 72px; /* Header height + margin */
}

现在将此 class fake-margin 添加到这些链接中，即：

<div id="Company" class="fake-margin">
<div id="Resources" class="fake-margin">
<div id="Signs" class="fake-margin">
<div id="Magnets" class="fake-margin">
<div id="Banners" class="fake-margin">

等等。它不会显示在您的 fiddle 中，因为 fiddle 没有固定的 header。 :)
