Navbarの下にあるコンポーネント

Question

パラグラフ、ヘッダー、ボタンなどのコンテナ要素がナビゲーションバーの下に表示されます。 navbarは固定トップのプロパティを持っています。私はこれ（twitter bootstrap navbar fixed top overlapping site）のような他のstackoverflowポストからの以前の提案を使用しました。しかし、何も私のために働くようです。これは私のnavbarのコードです。

<nav class="navbar navbar-expand-md navbar-dark bg-dark fixed-top"> 
     <div class="container"> 
      <a class="navbar-brand text-white" href="#"> Bacon Bacon</a> 
      <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation"> 
       <span class="navbar-toggler-icon"></span> 
      </button> 
      <div class="collapse navbar-collapse" id="navbarsExampleDefault"> 
       <ul class="navbar-nav ml-auto"> 
        <li class="nav-item active"> 
         <a class="nav-link text-white" href="#">Home</a> 
        </li> 
        <li class="nav-item"> 
         <a class="nav-link text-white" href="#">About Us</a> 
        </li> 
        <li class="nav-item"> 
         <a class="nav-link text-white" href="#">Services</a> 
        </li> 
        <li class="nav-item"> 
         <a class="nav-link text-white" href="#">Products</a> 
        </li> 
        <li class="nav-item"> 
         <a class="nav-link text-white" href="#">Contact</a> 
        </li> 
       </ul> 
      </div> 
     </div> 
    </nav> 

マイコンテナコード

<div class="container-fluid bg-overlay"> 
    <div class="row text-center"> 
     <h1>Loren Inpsum</h1> 
     <h4>Loren Inpsum Loren Inpsum Loren Inpsum Loren Inpsum </h4> 
     <button type="button" class="btn btn-primary btn-lg">Get Started</button> 
    </div> 
</div> 

マイCSS

@media (max-width: 979px) { 
      body { 
       padding-top: 70px; 
      } 
} 


      .navbar { 
      margin-bottom:0px; 
      background: #FFFFFF; 
      border-color: #FFFFFF; 
      padding-bottom:0px; 
      } 


      .bg-overlay { 
      background: linear-gradient(rgba(0,0,0,.7), rgba(0,0,0,.7)), url("https://unsplash.imgix.net/photo-1416339442236-8ceb164046f8?q=75&fm=jpg&s=8eb83df8a744544977722717b1ea4d09"); 
      background-repeat: no-repeat; 
      text-align:center; 
      background-size: cover; 
      background-position: center center; 
      color: #fff; 
      height: 450px; 
      padding-top: 0px; 
    } 

      div.container-fluid bg-overlay{ 
       margin-bottom:30px; 


      }

あなたはMQのpadding-top外を追加する必要が唯一のもの。

body { 
 
    padding-top: 60px; 
 
} 
 
@media (max-width: 979px) { 
 
      body { 
 
       padding-top: 70px; 
 
      } 
 
} 
 

 

 
      .navbar { 
 
      margin-bottom:0px; 
 
      background: #FFFFFF; 
 
      border-color: #FFFFFF; 
 
      padding-bottom:0px; 
 
      } 
 

 

 
      .bg-overlay { 
 
      background: linear-gradient(rgba(0,0,0,.7), rgba(0,0,0,.7)), url("https://unsplash.imgix.net/photo-1416339442236-8ceb164046f8?q=75&fm=jpg&s=8eb83df8a744544977722717b1ea4d09"); 
 
      background-repeat: no-repeat; 
 
      text-align:center; 
 
      background-size: cover; 
 
      background-position: center center; 
 
      color: #fff; 
 
      height: 450px; 
 
      padding-top: 0px; 
 
    } 
 

 
      div.container-fluid bg-overlay{ 
 
       margin-bottom:30px; 
 

 

 
      }
