Html 分离引导按钮

我想复制我的“提交”按钮。当我这样做的时候，似乎bootstrap认为复制是navbar的一部分，所以当我这样做style=“margin top:30px；”时，navbar基本上会增长，直到它到达按钮。你自己看看这里：我想知道如何把那个按钮变成自己的，这样我就可以在页面中移动它了。我尝试过一些方法，比如将按钮表单放入容器和行div中，但它们似乎不起作用

  <a class="navbar-brand" href="#"><img src="img/logo.png" style="position: relative; top: -7.5px;" /></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="#">Link</a></li>
    <li><a href="#">Link</a></li>
    <li class="dropdown">
      <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <span class="caret"></span></a>
      <ul class="dropdown-menu" role="menu">
        <li><a href="#">Action</a></li>
        <li><a href="#">Another action</a></li>
        <li><a href="#">Something else here</a></li>
        <li class="divider"></li>
        <li><a href="#">Separated link</a></li>
        <li class="divider"></li>
        <li><a href="#">One more separated linkk</a></li>
      </ul>
    </li>
  </ul>
  <form class="navbar-form navbar-left" role="search">
    <div class="form-group">
      <input type="text" class="form-control" placeholder="Search" size=60px>
    </div>
    <button type="submit" class="btn btn-default" value="Open Window" onclick="window.open('http://www.cnn.com')">Submit</button>
  </form>
  <ul class="nav navbar-nav navbar-right">
    <li><a href="#">Link</a></li>
    <li class="dropdown">
      <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <span class="caret"></span></a>
      <ul class="dropdown-menu" role="menu">
        <li><a href="#">Action</a></li>
        <li><a href="#">Another action</a></li>
        <li><a href="#">Something else here</a></li>
        <li class="divider"></li>
        <li><a href="#">Separated link</a></li>
      </ul>
    </li>
  </ul>
</div><!-- /.navbar-collapse -->

提交您只是忘记添加关闭

nav

HTML标记（看起来是这样的：

）。您的代码（基于JSFIDLE）如下所示：

<!-- Your Navbar starts here -->
<nav class="navbar navbar-default" role="navigation">
  <div class="container-fluid">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">

        <span class="icon-bar"></span>
        <span class="icon-bar"></span>

      </button>

避免将来出现类似问题的一个简单方法是使用文本编辑器，如或，每个编辑器都将显示开始标记是否与结束标记关联。不过别担心，我知道我还是经常犯这样的错误
