Question

我已经将我的网页设置了几个星期了。就在今天，我决定使用我的导航栏部分和元标记和链接，并将它们放在母版页上。当我这样做时，一切顺利，除了一件事。顶部信息部分背景在底部短缺。这几乎就像它没有在我的样式表中阅读height: 100%。这是我的主页，我把一些东西移到了。

  <body>

    <nav class="navbar navbar-default top-of-page">
  <div class="container">
    <!-- 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>

      <a class="navbar-brand" href="#"><img src='/CMS_Static/Uploads/313864614C6F6F/fv-logo-3.gif' align="left"/></a>
    </div>

    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
      <ul id="navLinks" class="nav navbar-nav">
        <li><a href="#">Home</a></li>
        <li><a href="#">Services</a></li>
        <li><a href="#">Locations</a></li>
        <li><a href="#">Prices</a></li>
        <li><a href="#">Contact</a></li>
      </ul>
    </div>
  </div>
</nav>

@renderbody()

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
    <script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa" crossorigin="anonymous"></script>    

  <script>  $(window).on("scroll", function() {
    var scrollPos = $(window).scrollTop();
    if (scrollPos <= 0) {
        $('.navbar-default').addClass('top-of-page');
    } else {
        $('.navbar-default').removeClass('top-of-page');
    }
});
   </script>
   @renderSection("scripts",false)
  </body>
</html>

这是我的顶部信息部分，背景为

<section class="topInfo">
    <div class="container">
        <div class="row">
            <div class="col-md-10 col-md-offset-1">
                <h1 class="topInfoText text-center">Aerial Drone Services, Stock Footage, and Affordable Prints</h1>
            </div>
            <div class="col-sm-4 col-sm-offset-4">
                 <a class="btn bannerBtn btn-block" href="#">Learn More</a>
            </div>
        </div>
    </div>
</section>

和topInfo类的样式

.topInfo {
        background-image: linear-gradient( rgba(0,0,0,.25), rgba(0,0,0,.25) ), url('/CMS_Static/Uploads/313864614C6F6F/exuma rocks 2.jpg');
        background-attachment: fixed;
        background-size: cover;
        background-repeat: no-repeat;
        background-position: center;
        height: 100%;
    }

Answer 1

height: 100%元素只能与父元素一样高。父母有多高？如果它是身体的直接孩子，请尝试在CSS中设置：

html, body {
   height: 100%;
}

背景图片不会填满屏幕
