Question

我的导航栏当前存在一些问题。现在它看起来像图像1，但我想使其看起来像图像2。我该怎么做？我必须在CSS上添加一些东西吗？

/* Nav Bar*/
.navbar-brand{
    height: 3.5rem;
}

.navbar-nav li {
    padding-right: 0.1rem;
}

.nav-link {
    font-size: 1.1rem;
    font-weight: 500;
}

.nav-item:hover {
    border-bottom: 1px solid #FF7200;
}

.nav
{
    
}

<body>
  <!--Navigation-->
  <nav class="navbar navbar-expand-md navbar-light bg-light fixed-top">
    <div class="container-fluid">
      <img class="navbar-brand" src="../img/IMG_0537.PNG" alt="KAJ Construction Logo"/>
      <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
      </button>
      <div class="collapse navbar-collapse" id="navbarResponsive">
        <ul class="navbar-nav ml-auto">
          <li class="nav-item active">
            <a class="nav-link" href="#section-Services" >Services</a>
          </li>
          <li class="nav-item">
            <a class="nav-link" href="#section-Gallery" >Gallery</a>
          </li>
          <li class="nav-item">
            <a class="nav-link" href="#section-Contact" >Contact Us</a>
          </li>
        </ul>
      </div>
    </div>
  </nav>

How it currently looks when services link is clicked How I want it to look like

Answer 1

添加一些内置的引导程序边距和填充，例如mt-3（mt表示margin-top）使用p-2（从两侧填充）2和3定义2rem或3rem使用它将修复

Answer 2

由于标题为flutter\bin，因此需要使页面内容的页边距等于其高度：

position: fixed

/* Nav Bar*/
.navbar-brand{
    height: 3.5rem;
}

.navbar-nav li {
    padding-right: 0.1rem;
}

.nav-link {
    font-size: 1.1rem;
    font-weight: 500;
}

.nav-item:hover {
    border-bottom: 1px solid #FF7200;
}

main{
    margin-top: 72px;
}
