将导航栏移动到下方 header bootstrap

Question

我是 bootstrap 的新手，我想知道是否有人可以就如何将导航栏放在 header 下方提供一些建议。这是我目前的两个代码：

Header:

        <div class="row">
            <div class="col-lg-12">
                <div class="intro-message">
                    <h1>HOST</h1>
                    <h3>two is better than one</h3>
                    <hr class="intro-divider">
                    <ul class="list-inline intro-social-buttons">
                        <li>
                            <a href="https://twitter.com/SBootstrap" class="btn btn-default btn-lg"><i class="fa fa-twitter fa-fw"></i> <span class="network-name">Twitter</span></a>
                        </li>
                        <li>
                            <a href="https://github.com/IronSummitMedia/startbootstrap" class="btn btn-default btn-lg"><i class="fa fa-github fa-fw"></i> <span class="network-name">Github</span></a>
                        </li>
                        <li>
                            <a href="#" class="btn btn-default btn-lg"><i class="fa fa-linkedin fa-fw"></i> <span class="network-name">Linkedin</span></a>
                        </li>
                    </ul>
                </div>
            </div>
        </div>

    </div>

导航栏：

<nav class="navbar navbar-default navbar-fixed-top topnav" role="navigation">
        <div class="container topnav">
            <!-- Brand and toggle get grouped for better mobile display -->
            <div class="navbar-header">
                <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
                    <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 topnav" href="/">Host</a>
            </div>

        <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
            <ul class="nav navbar-nav navbar-right">
                <li>
                    <a href="#">Login</a>
                </li>
                <li>
                    <a href="#">Sign up</a>
                </li>
            </ul>

            <form class="navbar-form navbar-right" role="search">
              <div class="form-group">
                <input type="text" class="form-control" placeholder="Search">
              </div>
              <button type="submit" class="btn btn-default">Submit</button>
            </form>

        </div>
        <!-- /.navbar-collapse -->
    </div>
    <!-- /.container -->
</nav>

如有任何建议和提示，我们将不胜感激。我对编程也很陌生，所以很好的解释！ =)

Answer 1

改变一下

navbar-fixed-top

到 navbar-top

编辑第二个答案：

改成

<nav id="myNav" class="navbar navbar-default" role="navigation">

并且您需要添加 jquery 引用和这个小脚本。

var headerHeight = 200;

$(window).bind('scroll', function () {
if ($(window).scrollTop() > headerHeight) {
    $('#myNav').removeClass('navbar-top');
    $('#myNav').addClass('navbar-fixed-top');
} else {
    $('#myNav').removeClass('navbar-fixed-top');
    $('#myNav').addClass('navbar-top');
}
});

基本上，它的作用是检查您从顶部滚动了多少，当您超过 header 高度时，它会修复导航以保持在顶部。您只需将 headerHeight 值更改为您的 header 高度。
