Question

我一直在研究我的第一个网站用于学习目的并遇到这个问题：

每当我链接到同一页面上的特定位置时，它都会按预期打开，但顶部会被导航栏覆盖。

<body data-spy="scroll" data-target="#myNavbar" data-offset="50">
   <nav id="myNavbar" role="navigation" class="container-fluid navbar navbar-default navbar-fixed-top">
      <div class="container">
         <div class="navbar-header">
            <button type="button" data-target="#navbarCollapse" data-toggle="collapse" class="navbar-toggle">
               <span class="sr-only"></span>
               <span class="icon-bar"></span>
               <span class="icon-bar"></span>
               <span class="icon-bar"></span>
            </button>
            <a href="#" class="navbar-brand"></a>
         </div>
         <div id="navbarCollapse" class="collapse navbar-collapse">

            <ul class="nav navbar-nav navbar-right">
               <li><a href="#section1">Home</a></li>
               <li><a href="#section2">About</a></li>
               <li><a href="#section3">Portfolio</a></li>
               <li><a href="#section4">Contact</a></li>
            </ul>
         </div>
      </div>
   </nav>

   <div class="jumbotron" id="section1">
      <h1 class="header"></h1>
      <hr class="style" />
      <un class="list-inline">
         <li>
            <a href="#">
               <span class="glyphicon glyphicon-chevron-left"></span> Facebook
               <span class="glyphicon glyphicon-chevron-right"></span>
            </a>
         </li>
         <li>
            <a href="#">
               <span class="glyphicon glyphicon-chevron-left"></span> GitHub
               <span class="glyphicon glyphicon-chevron-right"></span>
            </a>
         </li>
         <li>
            <a href="#">
               <span class="glyphicon glyphicon-chevron-left"></span> LinkedIn
               <span class="glyphicon glyphicon-chevron-right"></span>
            </a>
         </li>
      </un>
   </div>
</body>

有没有办法让它链接到导航栏下方，以便它不会覆盖部分的顶部？

尝试使用身体的填充顶部，但没有用。

（我能够通过链接到单独的div并通过CSS调整它们来解决这个问题，但是在执行bootstrap后，覆盖整个部分的scrollspy divs已被定位，因此返回了问题。）

P.S。：没有使用JS / Query。

这可能有助于或给你一些想法;你基本上只是在navbar-fixed-top课程下一起使用两个导航栏，这样他们就可以一起滚动。

body {
  margin-top: 100px;
  position: relative;
}
.navbar.nav-lower {
  height: 20px;
  background: #f5f5f5;
  border-radius: 0;
  border: none;
  margin-bottom: 0;
}
.nav-lower .navbar-toggle,
.nav-lower .navbar-toggle:focus,
.nav-lower .navbar-toggle:hover {
  border: none;
  background: none;
}
.navbar.nav-lower > li {
  display: inline-block;
  width: 33%;
  text-align: center;
}
#section1 {
  padding-top: 100px;
  height: 500px;
  color: #fff;
  background-color: #1E88E5;
}
#section2 {
  padding-top: 100px;
  height: 500px;
  color: #fff;
  background-color: #673ab7;
}
#section3 {
  padding-top: 100px;
  height: 500px;
  color: #fff;
  background-color: #ff9800;
}
#section4 {
  padding-top: 100px;
  height: 500px;
  color: #fff;
  background-color: #00bcd4;
}
@media (max-width: 767px) {
  .nav-lower .navbar-collapse {
    text-align: left;
    background: #f5f5f5;
  }
}
@media (min-width: 767px) {
  .navbar.navbar-default.nav-lower .navbar-inner {
    padding: 0;
  }
  .navbar.navbar-default.nav-lower .nav {
    margin: 0;
    display: table;
    width: 100%;
  }
  .navbar.navbar-default.nav-lower .nav > li {
    display: table-cell;
    float: none;
  }
  .navbar.navbar-default.nav-lower .nav > li > a {
    text-align: center;
  }
}
