Question

我正在使用Boostrap 3构建一个简单的登录页面。我无法将我的jumbotron的内容垂直居中。我也很难通过我的透明导航栏显示jumbotron;它目前固定在导航栏的底部。到目前为止，这是我的代码：

HTML：

<!DOCTYPE html>

<html>
    <head>
        <!-- Normalize.CSS -->
        <link rel="stylesheet" src="//normalize-css.googlecode.com/svn/trunk/normalize.css" />

        <!-- Latest compiled and minified CSS -->
        <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">

        <!-- Optional theme -->
        <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap-theme.min.css">

        <!-- Custom CSS -->
        <link rel="stylesheet" href="style.css">

        <title>Hair by Dennis</title>
    </head>
    <body>
        <nav class="navbar navbar-default">
          <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="#">Hair by Dennis</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 navbar-right text-center">
                <li><a href="#">Services</a></li>
                <li><a href="#">About Me</a></li>
                <li><a href="#">My Work</a></li>
                <li><a href="#">Contact Me</a></li>
              </ul>
            </div><!-- /.navbar-collapse -->
          </div><!-- /.container-fluid -->
        </nav>

        <!-- Jumbotron -->
        <div class="jumbotron">
            <div class="container text-center">
                <h1>Hair by Dennis</h1>
                <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
                <!-- Triggers Modal -->
                <a href="#" class="btn btn-primary btn-lg outline sharp" data-toggle="modal" data-target="#makeAnAppointmentModal">Make an Appointment</a>
            </div>
        </div>

        <!-- Latest compiled and minified JavaScript -->

        <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
    </body>
</html>

CSS：

.navbar, .jumbotron {
    margin-bottom: 0;
}

.navbar {
    border-radius: 0;
    background: none;
}

.navbar .nav > li > a {
    color: #F44336;
}

.navbar-default .navbar-brand {
    color: #F44336;
    padding-left: 50px;
}

.jumbotron {
    border-radius: 0;
    background-color: #F44336;
    color: #FFF;
    height: 520px;
}

/***********************

.btn.outline {
    background: none;
    padding: 12px 22px;
}
.btn-primary.outline {
    border: 2px solid #FFF;
    color: #FFF;
}
.btn-primary.outline:hover, .btn-primary.outline:focus, .btn-primary.outline:active, .btn-primary.outline.active, .open > .dropdown-toggle.btn-primary {
    color: #F44336;
    background-color: #FFF;
}

.btn-primary.outline:active, .btn-primary.outline.active {
    border-color: #FFF;
    color: #FFF;
    box-shadow: none;
}

/***********************
  CUSTOM BTN VALUES

.btn {
    padding: 14px 24px;
    border: 0 none;
    font-weight: 700;
    letter-spacing: 1px;
    text-transform: uppercase;
}
.btn:focus, .btn:active:focus, .btn.active:focus {
    outline: 0 none;
}

.sharp {
    border-radius: 0;
}

如果我的问题不清楚，请告诉我。任何帮助表示赞赏！

将此添加到您的CSS中，垂直居中应该有效：

.jumbotron > .container {
   position: relative;
   top: 50%;
   transform: translateY(-50%);
}
