<div class="firstPart"> 
      <nav class="navbar navbar-default navbar-fixed-top"> 
       <div class="container-fluid"> 
        <!-- Brand and toggle get grouped for better mobile display --> 
       <div class="navbar-header"> 
        <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false"> 
         <span class="sr-only">Toggle navigation</span> 
         <span class="icon-bar"></span> 
         <span class="icon-bar"></span> 
         <span class="icon-bar"></span> 
        </button> 
         <a class="navbar-brand" href="#">Gustoso</a> 
       </div> 

      <!-- Collect the nav links, forms, and other content for toggling --> 
      <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"> 
       <ul class="nav navbar-nav"> 
        <li class="active"><a href="#">Welcome<span class="sr-only">(current)</span></a></li> 
        <li><a href="#">Menu</a></li> 
        <li><a href="#">Reservation</a></li> 
        <li><a href="#">News</a></li> 
        <li><a href="#">Contact</a></li> 
       </ul> 
      <ul class="nav navbar-nav navbar-right"> 
       <li><i class="fa fa-twitter"></i></li> 
       <li><i class="fa fa-twitter"></i></li> 
       <li><i class="fa fa-twitter"></i></li> 
      </ul> 
       </div><!-- /.navbar-collapse --> 
      </div><!-- /.container-fluid --> 
     </nav> 

    </div> <!--.firstPart--> 
    <section class="headerArea"> 
     <h1>Pastry With Love</h1> 

    </section><!--.headerArea--> 

這裏是CSS：

body { 
    margin: 0; 
    padding: 0; 
    font-size: 14px; 
    color: black; 
    background-color: #f3f1f2; 
} 
.firstPart { 
    background: url('bannerFirst.jpg'); 
    background-repeat: no-repeat; 
    background-size: cover; 
    background-position: center; 
    min-height: 100%; 
    padding-top: 0px; 
    padding-bottom: 957px; 
} 
.navbar-default { 
    background: none; 
} 
.navbar-default .navbar-collapse { 
    border-color: #e7e7e7; 
    background-color: transparent; 
} 
.backgroundImage { 
    width: device-width; 
} 
.nav navbar-nav { 
    font-size: 14px; 
    font-family: "Alegreya"; 
    color: rgb(255, 255, 255); 
    text-transform: uppercase; 
    line-height: 1.714; 
    position: absolute; 
    left: 413.844px; 
    top: 23.002px; 
    z-index: 275; 
    display: inline-block; 
    padding-right: 44px; 
    padding-top: 4px; 
} 
.headerArea { 
    color: white; 
    font-size: 30px; 
    margin-top: -360px; 
    margin-left: 375px; 
}

使用背景位置：0像素50像素;從特定位置開始背景圖像。
